Environment variables in alphabetical order

Restriction: This topic applies only when the Enterprise Server feature is enabled.

C

CASSPOOL_LOCK_RETRY_COUNT
Category: JES
If errors are experienced by the spool module, the number of times it retries to obtain a record lock can be adjusted using this environment variable.

Syntax

SET CASSPOOL_LOCK_RETRY_COUNT=count

Values

count The number of retries made to obtain a record lock.

Default

If not specified, this variable defaults to 20.

CCITIMEOUT

Allows the specification, in tenths of seconds, of the maximum time out period that will be used with any LSC style application, such as Drag and Drop, SourceConnect, or the Monitor. The maximum value that can be used is 2,147,483,647.

Syntax

SET CCITIMEOUT=value

Default

The default is 1200 (2 minutes).

Example
This example sets the value to 4 minutes:
SET CCITIMEOUT=2400 
CCIERRLOG
Specifies the output location and filename of ccierr.log content which tracks first-instance errors reported from the operating systems. CCIERRLOG overrides any entries found in CCI.INI, where the syntax and content is explained in detail.
CCITCP2
Instead of using the CCI Configuration Utility to set the TCP address of the machine running the CCITCP2 registration daemon the environment variable "CCITCP2" can be used instead. This may be useful if you need different processes on the same machine to contact different registration daemons.

Syntax

set CCITCP2=hostname

Parameters

hostname is the TCP hostname or dotted decimal IP address of the machine running the CCITCP2 daemon you wish to contact from that session.

Comments

The environment variable value will always take precedence over any value set using the Configuration Utility. To restore a process to using the value set by the Configuration Utility simply set the environment variable to an empty string, such as

set CCITCP2=

Alternatively, if this environment variable is set system-wide (by creating a system variable in the system environment settings, or by using a CONFIG.SYS file) then this value will always take precedence over any value set using the Configuration Utility.

CCITCP2_PORT
The port that is being used for the registration process.

Syntax

set CCITCP2_PORT=port
Parameters
  • port The port on which the CCITCP2 registration program operates.
CCITCPS
To start a CCI server on a fixed port, you can associate the Server Name with the port value by using the CCITCPS_ environment variable instead of appending the information on the Server Name itself.

Syntax

set CCITCPS_server_name=port

Parameters

  • server_name is the name of the CCI server
  • port is the fixed TCP post to use

Note that this will only work if the server application process is started in the same session or process that has this environment variable set.

Example

set CCITCPS_server_name=MFPORT:3000
CCITCPT

If a client is known to be trying to connect to a server with Server Name server_name, and the TCP address and port (e.g. 3000) that the server is using is known, then the client can be made to connect directly to it by setting this environment variable.

Syntax

CCITCPT_server_name=MFNODE:server_hostname,MFPORT:port_number

Note that this can be used instead of setting the client Machine Name value. This is useful if the Machine Name value the client specifies cannot be altered by an application defined method.

Parameters

  • server_name The server to which the client is trying to connect.
  • server_hostname The TCP address.
  • port_number The TCP post number.

Example

CCITCPT_server1=MFNODE:server2,MFPORT:3000
CCITRACE
Part of the process to enable CCI tracing is to specify the degree of information that will be traced, which can be done by setting the CCITRACE environment variable as follows:

Syntax

CCITRACE=filename [options]
Parameters
  • filename The name of the log file you want the trace output to go to. If you do not specify this parameter, the log file ccitrace.log is created in the current directory with all options set to their default states.
  • options Any, or all, of the following:
/F or -F logs the details of CCI API calls to the trace file. The default is OFF, unless a filename any other trace option is specified, in which case it is always ON.
/P or -P logs the details of protocol-level calls to the trace file. The default is OFF. If this flag is OFF, then only the details of the CCI user-level API will be traced. If this flag is ON, the level of function tracing may be greatly increased.
/D or -D logs the contents of all buffers passed to and from the CCI functions. The default is OFF. Data tracing may not be allowed if the application has been coded to prohibit data tracing for security reasons.

So to create a CCI trace file with the default name of ccitrc1.trc (with matching ccitrc1.idx file) which traces CCI API function flow, along with the underlying protocol function flow, but with no tracing of the user data passed to these calls, the value of the CCITRACE environment variable would be /P.

The CCI.INI file can also be used to control trace options, but any values specified by the CCITRACE environment variable will take precedence.

COBCONFIG

Specifies a run-time configuration file that tailors the run-time configurable options in some way.

Syntax

SET COBCONFIG=pathname

Parameters

  • pathname The name of the COBOL configuration file that tailors the runtime

Comments

If $COBCONFIG is not set then the file $COBDIR/etc/cobconfig is searched for instead.

Example

SET COBCONFIG=/home/mydir/cobconfig
COBCONFIGJVM
Specifies a Java properties file that tailors the run-time configurable options for Java Virtual Machine applications. Use this instead of COBCONFIG in COBOL applications intended for use on a Java Virtual Machine.

Values

  • The location of a properties file.
COBCONFIG.BLOCK
The location of the application configuration file.
COBCPY

Specifies the directory or directories that the Compiler and Animator should search for copyfiles.

Syntax

SET COBCPY=pathname[:pathname]...

Parameters

  • pathname

    A directory that the Compiler and Animator are to search when looking for copyfiles. When more than one pathname is present, a null pathname represents the current working directory.

Example

SET COBCPY=/home/group/sharedcopy::mydir/mycpy

causes the Compiler to search for a copyfile in /home/group/sharedcopy, then in the current directory and finally in ./mydir/mycpy until either the copyfile is found or it can be considered not found.

COBDATA
Specifies one or more locations, separated by ; (Windows) or : (UNIX), in which to search for data files at run time. As long as the file assignment does not contain a sub-path (that is, a string containing \ or /) then the file assignment is appended to each location specified by COBDATA in order to locate the file.
Note: Users modernizing RM/COBOL or ACUCOBOL-GT legacy code can use a sub-path in the file assignment, but only by compiling with the relevant DIALECT or IDXFORMAT values for the respective File Handling systems; setting these values in the File Handling configuration file is not sufficient to achieve this.

Specifies the directory or directories that the run-time system is to search for data files. Provides you with the facility to map data files globally, thus enabling you to put working data files in a directory whose name is not known until run time.

Syntax

COBDATA=pathname[:pathname]...
Parameters
  • A list of search directories, each item separated by a semicolon. The runtime system is to search these when looking for application data files. When more than one pathname is present, a null pathname represents the current working directory.

Comments

COBDATA affects the compiler and other utilities. During compilation, for example, program source is regarded as a data file by the compiler. If you intend to use any COBOL development system utilities, we recommend that the COBDATA value starts with a colon (:).

COBDATA is considered set if there is an environment variable of this name in your environment space, and its value is non-empty.

The full mapping order for files is:

  1. Any dd_ environment mappings
  2. Any ASSIGN TO EXTERNAL mappings
  3. Any COBDATA environment variable mappings

For multiple directory paths specified either in the COBDATA environment variable or a dd_ environment variable, the system searches the first directory specified followed by a slash (/) as a prefix to the user name.

If the filename is not found, or is not readable, the search continues with the next directory until the final directory has been searched. If no file is found, the first directory is used if a file is to be created.

Any dd_ and COBDATA mappings are ignored for any filename that starts with a hyphen () or a slash (/). In addition, it is illegal to have a hyphen in an environment variable name.

When using this facility, you should not use a filename that starts with "COB... "(these are reserved for the COBOL system).

You can use the COBDATA environment variable for files open in any mode (including OUTPUT) and for fixed or variable length files. If you are using indexed files, both the data and index files must be in the same directory.

The COBDATA environment variable affects file deletes, using the rules given here, as well as file opens.

If you intend to use COBOL development system programs, we recommend that you first unset COBDATA, as many of these programs open data files and are thus affected by the value of COBDATA. If you have to set COBDATA, you should include the paths :$COBDIR/dynload/helptbox.lbr and :$COBDIR/dynload/check.lbr at the beginning of the COBDATA value. If you want to see the Animator Help pages, also include COBDIR/dynload/advanim.lbr.

Note: Users modernizing RM/COBOL or ACUCOBOL-GT legacy code can use a sub-path in the file assignment, but only by compiling with the relevant DIALECT or IDXFORMAT values for the respective File Handling systems; setting these values in the File Handling configuration file is not sufficient to achieve this.

Example

SET COBDATA=:demo:/home/data:progs

causes COBDATA to be set to instruct the runtime system to search for data files in the current directory, then in the directory ./demo, then in the directory /home/data and finally in ./progs.

COBDIR

Specifies the directory where the required Micro Focus COBOL system is installed. Many of the COBOL system components and utilities require and use this information. If the COBDIR environment variable is not set then the COBOL system acts as if it had been set to the default COBOL system directory.

Syntax
SET COBDIR=pathname

Parameters

  • pathname The directory that contains the required Micro Focus COBOL system software.

Comments

The Micro Focus COBOL system is normally installed in the default COBOL system directory and so does not require COBDIR to be set. COBDIR only needs to be set when your COBOL system has been installed in a different directory such as when more than one version of the COBOL system is available at the same time.

Example

SET COBDIR=/home/products/cobse20

This causes the Cob utility to search the directory /home/products/cobse20 for the Micro Focus COBOL system software.

COBJVM

Specifies which Java Virtual Machine (JVM) to load.

Syntax
SET COBJVM=platform_nnn

Parameters

platform_nnn where

platform is a threecharacter code that indicates the platform on which you are running Server Express, for example:
  • ibm IBM AIX
  • unx SCO UnixWare
  • sun Oracle SPARC
nnn indicates the version of the JVM, for example:
  • 122 Version 1.2.2
  • 130 Version 1.3.0

Comments

You might need to set COBJVM if you are developing distributed applications with both COBOL and Java components.

Example

SET COBJVM=ibm_122
COBKEYTIMEOUT

Specifies the maximum elapsed time, in tenths of a second, for the connected terminal to transmit any valid escape sequence to the runtime system.

When a terminal key is depressed, the terminal might send in response a single character or a group of characters to the runtime system. Typically, such a group of characters starts with an escape character and the group of characters is known as an escape sequence. A terminal might send an escape sequence for one depression of a function key. It might also send the same sequence of characters for a depression of the Escape key followed by the depression of one or more alphabetic or numeric data keys. The only difference apparent to the runtime system is the interval between the arrival of each character; the user cannot type as fast as the escape sequence is generated by the terminal.

If a terminal is connected over a network that sends the characters to the runtime system in discrete packets, then the network can alter the intervals between each character arriving at the runtime system. COBKEYTIMEOUT is available to help compensate for typical network delays so the runtime system identifies escape sequences correctly.

Syntax

SET COBKEYTIMEOUT=n

Parameters

n A number in the range 1 through 126 that represents the maximum elapsed time required for a terminal to transmit any valid escape sequence to the runtime system over the line or network connection. On encountering a lone Escape character, the runtime system waits n tenths of a second before assuming that the character does not introduce an escape sequence. The runtime system calculates an appropriate default value for n from the baud rate of the terminal.

COBLANG
The language environment in which your COBOL program runs.
Values
  • A COBOL language environment (LE) value.
COBLPFORM
This configuration variable is used to define and print to printer channels C01-C12. Specify the line numbers for each channel with the COBLPFORM configuration variable. Null entries are ignored. Those channels that have line number zero, function-names S01-S052, CSP, or are undefined, are set to line 1.

Example 1:

COBLPFORM 1:3:5:7:9:11:13:15:17:19:21:23

In this example C01 equals 1, C02 equals 3, and so on.

Example 2:

COBLPFORM :3::5: :9

In this example, C01 equals 3, C02 equals 5, C03 equals 1, and C04 equals 9. You can specify only a single line number for each channel.

In example 2 above, channels C05 - C12 are undefined. If a print statement specifies channel C05 - C12, the line is printed at line 1. In addition, in the example shown, C03 equals 1 because its value is a space and therefore undefined.

Any WRITE BEFORE/AFTER PAGE statements cause positioning to be at line 1. Each line advance increases the line number by one. A request to skip to a line number less than or equal to the current line causes a new page to begin. The appropriate number of line feeds are then generated.

COBMAINSTACK

Specifies the size of the main stack.

Syntax

SET COBMAINSTACK=n

Parameters

n A number in the range 1 through nnn that represents the size of the main stack.

Comments

You might need to set COBMAINSTACK in any of the following circumstances:

  • If you are deploying OO COBOL Enterprise JavaBeans (EJBs) to WebSphere on the AIX platform
  • If you are using the multi-threaded run-time system

    If you have IF STATEMENTS with a very large number of ELSE clauses

COBPATH

Specifies the directory or directories that the runtime system is to search for dynamically loadable .int and .gnt files, or callable shared objects.

Syntax

SET COBPATH=pathname[:pathname]...

Parameters

pathname A list of search directories, each item separated by a semicolon, that the runtime system is to search for a dynamically loadable program (.int, .gnt or callable shared object) file. When more than one pathname is specified, a null pathname represents the current working directory.

Example

SET COBPATH=u:/home/mydir/srclib:otherlib
COBPRFDIR
Location of .ipf files created by programs compiled with the PROFILE compiler directive.
Values
  • A list of search directories, each item separated by a semicolon.
COBPRINTER

Specifies the name of a print spooler that is to receive, via its standard input stream (stdin), output from any DISPLAY UPON PRINTER statement.

Syntax

SET COBPRINTER=command-line

Parameters

  • command-line A command line supported by your system and that can be executed by the system shell. Typically, it is simply the name of a print spooler or other executable, but if the shell is escaped when setting the value then any command-line arguments can be used.

Comments

Each DISPLAY UPON PRINTER statement executed by your COBOL program causes a new invocation of command-line. Each invocation receives the data referenced in the DISPLAY statement, and is followed by a system end-of-file condition.

Example

SET COBPRINTER="myspooler -a $TMPDIR\spoolfile"
COBSSL
If using SSL connections specifies the location of the DemoCA directory. If not found, SSLDIR is inspected instead.
COBSW
Specifies the run-time system switch settings for the run-time system to observe when running an application.

Syntax

SET COBSW=[+/-}s...
Parameters

A list of the runtime switches to set or unset.

  • + sets a switch.
  • - un-sets a switch.

Example

SET COBSW=+0+D

This enables runtime switch 0 and the ANSI COBOL debug switch.

CODEWATCH_SRCPATH
The location of source files for the debugger to use if none are found in directories specified when invoking CodeWatch
Values
  • A list of search directories, each item separated by a semicolon.
CODEWATCH_STBPATH
The location of STB files for the debugger to use if none are found in directories specified when invoking CodeWatch.
Values
  • A list of search directories, each item separated by a semicolon.

D

DB2DBDFT
The default database for the DB2 SQL precompiler to process SQL statements against.

Values

  • The location and name of the default database.

E

ENTRYNAMEMAP
Specifies the locations of entry name map files to be used.

Syntax

SET ENTRYNAMEMAP={filename|directory}; ...

Parameters

filename An entry map file.

directory A directory containing an entry name map file. The name of the entry name map file must be mfentmap.dat.

Comments

You must set the entry_name_mapper tunable to enable entry point mapper support.

If ENTRYNAMEMAP is not set, the runtime system searches for an entry name map file called mfentmap.dat in each folder specified by the COBDIR environment variable.

If the runtime system finds more than one entry name map file and same entry point is defined differently in different files, precedence is given to the definition in the entry name map file that was found first. To change the order in which the runtime system finds entry name map files you need to change the order in which the files appear in the COBDIR or ENTRYNAMEMAP environment variable paths.

ES_ALLOC_EXPAND
The default value is Y, which expands an environment variable when used to specify an allocation path. Set to N to override this behavior, which is to not expand the variable used in the path.

Syntax

SET ES_ALLOC_EXPAND=value

Values

Y Expands an environment variable used to specify an allocation path.

N Do not expand the variable used in the path.

Default

The default value is Y.

ES_ALLOC_OVERRIDE

Values

rules-file The file path and name of the dataset rules file.

ES_CERT_REG
Specifies the directory in which the cascertreg user certificate utility should store its registrations.
Syntax
SET ES_CERT_REG=pathname
Values

pathname Pathname of the directory where registrations are stored.

Default

By default no directory is specified. In this case it must be specified on the cascertreg command.

ES_CESN_NO_OS390
Overrides the default behaviour CESN transaction response for invalid user credentials. Default behaviour reports "Your userid is invalid" or "Your password is invalid".
Syntax
SET CESN_NO_OS390=value
Values
  • Setting this variable to any value causes CESN to produce an invalid credential message instead of a specific invalid user or invalid password message.
Default

Specific invalid user/password messages will be produced.

ES_CONSOLE_LOG
Sends console messages to the Windows Event Log.
Note: ES_CONSOLE_LOG is deprecated, and provided for backward compatibility only. We recommend that you use MFDS configuration options instead.

ES_CONSOLE_LOG=port
export ES_CONSOLE_LOG
Values

Can be any combination of the following:

  • I - Send informational messages to the Windows Event Log.
  • W - Send warning messages to the Windows Event Log.

Stops CSKL writing messages to console.log
Syntax
ES_CSKL_NO_MSG_CONSOLE=value
Values
  • Any. CSKL messages are not written to the console log.
Default
If this is not set, CSKL messages are written to the console log.
ES_DDBG_PORT_RANGE
A range of ports to use for dynamic debugging.
You specify a range of port numbers separated by a hyphen or a comma; the second port number must be greater than the first.
Syntax
ES_DDBG_PORT_RANGE=value
Values
  • low_port-high_port
Default
If this is not set, dynamic debugging will use random ports.

Example

ES_DDBG_PORT_RANGE=8001-8040 
			 
ES_DISABLE_DFLTUSR_SIGNON
Disables the default user ("mfuser") signon when invoking ES Monitor & Control (ESMAC).
Syntax
ES_DISABLE_DFLTUSR_SIGNON=value
Values
  • Y or y Having logged on to ES administration via your MFDS internal security account, you no longer receive the auto logon as "mfuser" when accessing ESMAC.
Default
If this is not set, mfuser will be used as the default user to sign in to ESMAC.
ES_ESMAC_DISP_MAX_OVERRIDE
Limits the number of lines shown when viewing an individual catalog entry in the ESMAC catalog view.
Syntax
ES_ESMAC_DISP_MAX_OVERRIDE=value
Values
  • An integer number denoting how many ESMAC catalog view lines to display.
Default
10000
ES_HSF_CFG
Enables you to configure a number of additional fields to appear in the HSF record displayed in the .csv file (cashsf-a.csv or cashsf-b.csv).

Syntax

SET ES_HSF_CFG=cfg-options

Parameters

Define cfg-options using the following syntax:
field_name=value;[field_name=value;]...
using the following values:
Field name Range Default
CUSTOM 0-5 0
CICSF 0-20 5
TSQ 0-20 5
TDQ 0-20 5
Note: If a field is not explicitly set, or the value specified is out of range, the default value for the field is used.

For example: ES_HSF_CFG=CUSTOM=2;CICSF=10;TSQ=32 generates 2 custom fields, 10 CICS file fields, 5 TSQ fields and 5 TDQ fields.

Custom fields are written to using the ES_WRITE_CUSTOM_HSF library routine.

ES_MAX_CATALOG_LINES
Restricts the number of entries displayed in ESMAC catalog view.
Syntax
ES_MAX_CATALOG_LINES=number
Values
  • number The number of lines to display. The maximum is 99999.
Default
The default is 5000.
ES_MEM_STRATEGY
Selects the types of memory processes supported.
Note: Note that memory strategy can also be set via the memory_strategy runtime tunable.
ES_OLD_DYN_PDS
Determines the resulting behavior of dynamic PDS members when specified in a JCL DD statement.

Values

Y Enables previous default behavior of cataloging and creating the physical files for dynamic PDS when referenced in a JCL DD statement.

N Physical files for dynamic PDS members are only created and cataloged when created using the JCL utility or by a user program.

Default

The default value is N.

ES_OLD_SEC_TSTD
Prevents security being enforced for TS or TD queues that are not declared in the security repository.

ES_PROG_PATH
Set ES_PROG_PATH=Y to display the program's load path in the JESYSMSG and SYSLOG datasets.
Note: This is only applicable for native enterprise server regions.
ES_RLS_FILE_SUPPORT
If a record is locked because a program is doing a read for update, and the application needs to ensure that no other program can access that record, you can set this environment variable to avoid returning a dirty record until the program holding the lock has completed. The timeout in fileshare also needs to be set to 0 using /t 0 in the fileshare configuration file.

Syntax

SET ES_RLS_FILE_SUPPORT=value

Values

  • Y|y - Stops dirty records being returned when a record is locked by another process.

Default

RLS file support is off.

ES_SEP_DORMANT_TIME
Allows override of Transient SEP dormant time. Rather than automatically terminating transient SEPs on completion of a stateful request, the server manager allows a period of inactivity before scheduling their termination. This allows new requests to re-use the SEP rather than starting a new instance. This environment variable allows the period of inactivity to be controlled.

Syntax

ES_SEP_DORMANT_TIME=seconds

Values

  • seconds Number of seconds' inactivity.

Default

Transient SEPs are terminated after 2 seconds of inactivity.

ES_SERVER
The default server name (used if no -r switch is specified on casstart or casstop).

Syntax

ES_SERVER=name

Values

  • name The server name.

Default

ESDEMO/ESDEMO64

ES_SYSOUT_HOLD
The status of the SYSOUT files are set to Out Hold.
ES_USR_DFLT_ESMAC
Allows you to override the default user when no user is logged on for ESMAC authentication.

Syntax

SET ES_USR_DFLT_ESMAC=user

Values

  • user - the default user name.

Default

mfuser

ES_ESM_DISABLE_DFLTUSER_ESMAC
Allows you to disable the default ESMAC user in order to increase the security of your server. Disables the DEFAULT button on the logon screen and forces users to always enter a valid userid and password.

Syntax

ES_ESM_DISABLE_DFLTUSER_ESMAC=value

Values

  • Y|y - Default ESMAC user is disabled.

Default

Default ESMAC user is not disabled.

ES_XA_????_NB_RETRIES
Operates in conjunction with ES_XA_CONNECT. Sets the number of connection re-tries when attempting to connect to a resource.

Syntax

ES_XA_????_NB_RETRIES=nnnn

Values

  • ???? is the XA ID defined in MFDS.
  • nnnn is the number of subsequent XA call failures allowed before the SEP is recycled and the switch disabled.

Default

5 retries (ES_XA_RECONNECT must have been set).

ES_XA_LOG_SUPPRESS
Suppresses XA logging and the recovery of in-doubt XA transactions.

Syntax

ES_XA_LOG_SUPPRESS=value

Values

  • Y|y - XA logging is suppressed.

Default

By default no value is specified and XA logging is not suppressed.

ES_XA_RECONNECT

If this environment variable is set, when an error occurs on a call to XA, the server recycles the SEP and attempts to reconnect to the Resource Manager. The ES_XA_????_NB_RETRIES variable specifies the number of XA call failures allowed before the SEP is recycled and the switch disabled.

Syntax

SET ES_XA_RECONNECT=user

Values

  • Any value.

Default

No value is set and the XA reconnect feature is not enabled.

EXTFH
Specifies a configuration file for the Callable File Handler.

Syntax

SET EXTFH=filename.cfg

Parameters

filename.cgf The name of the configuration file.

Example

SET EXTFH=/home/mydir/myconfig.cfg

F

FHREDIR
Specifies a configuration file to be used by the Fileshare Client.

Syntax

SET FHREDIR=filename.cfg

Parameters

filename.cfg The name of the configuration file.

Example

SET FHREDIR=/home/mydir/myconfig.cfg
FS

Specifies a configuration file to be used by the Fileshare Server.

Syntax

SET FS=filename.cfg

Parameters

filename.cfg The name of the configuration file.

Example

SET FS=myconfig.cfg
FSCOMMS
Specifies that the Fileshare system is to run in single user mode.

Syntax

SET FSCOMMS="\$local"

Parameters

"\$local" Run the Fileshare System in single user mode.

H

HCOBND (deprecated)
Specifies a directory to be used for bind files generated by the DB2 External Compiler Module (ECM).
Note: HCOBND is deprecated, and provided for backward compatibility only. We recommend that you use either the BIND or the BINDDIR compiler directive option instead.

Syntax

SET HCOBND=pathname
HCOBND=pathname
export HCOBND

Parameters

pathname The directory that the DB2 ECM is to use to store bind files.

Example

SET HCOBND=d:\mydir\binds

Comments

The DB2 ECM uses the specified directory until the variable is unset or reset to a different directory. The DB2 Compiler directive option BIND overrides this environment variable.

I

ISPPROF
The location of ISPF dialog profiles.

J

JAVA_HOME
Specifies the location of the JDK.

L

LIB
The location of the DB2 LIB directory

M

MAINFRAME_FLOATING_POINT
Specifies the format to use for floating point data items. Possible formats are IBM hexadecimal and IEEE.

Syntax

SET MAINFRAME_FLOATING_POINT=fpstatus

Parameters

fpstatus Which format to use for floating point data items. This must be one of:

  • true Specifies that IBM hexadecimal format floating point data items are to be used.
  • false Specifies that IEEE format floating point data items are to be used.

Setting MAINFRAME_FLOATING_POINT to anything other than true has the same effect as setting it to false.

The setting of this environment variable can be overridden by the NATIVE-FLOATING-POINT directive.

MF_ALIAS
Specifies program aliases. Each set (pair) is 16 characters long - 8 characters for the program-name, and 8 characters for the alias. You can specify up to 10 pairs. This list is searched first and thus can potentially override the built-in list. If not found, the built-in alias table is searched.
MF_AMODE31ONLY
Indicates that all programs are AMODE(31).
MF_CBLQDA
Determines if QSAM files are dynamically allocated when processing an OPEN I-O or OPEN EXTEND statement for an optional file (that is, a file opened using the SELECT OPTIONAL syntax in the FILE-CONTROL paragraph) or a file opened for OUTPUT (regardless of whether it is optional or not). Permissible values are OFF and ON; the default is OFF, which specifies that dynamic allocation is not permitted.
This is an emulation of the CBLQDA Language Environment (LE) run-time option.
When set to ON, and your JCL contains a misspelled or no DD statement for the file being opened, a temporary file is created as a result of the OPEN statement, and then deleted after the program has run. For optional files opened for I-O or for EXTEND, you receive a return code of 05; for files opened for OUTPUT, you receive a return code of 00.
This variable has no effect on VSAM applications or the JCL utility programs.
Note: For programs that use ESDS files and have this variable set ON, ensure that FILETYPE is set to 15 or 16; otherwise these files will be affected by the variable, and treated as QSAM files.
MF_CHARSET
Specifies the system character set (ASCII or EBCDIC).
MF_DUPJOBS
Enables jobs with identical names to run.
Values:
  • Y (Default)
  • N

MFREXX_OR
One or more characters to be used for the OR operator in addition to REXX's default, which is "|".
Values
  • One or more characters for each operator; each character you specify is used in addition to the default operator. Each additional character must be defined within single or double quotes, or in hexadecimal. Separate multiple characters with a space or a comma.

Specifies whether to use SUBI or ASUBI.
Values
  • SUBI
  • ASUBI
MFSYSCATDIR
The location of the system catalog directory.
MFTRACE_ANNOTATIONS
The location of the trace files.

The location of the CTF log files.
MFTSO_DEBUG
Controls the display of debug messages.
MFUSER
The default User ID.
MFUSERCAT_LOC
User catalog location
MULTMFENTMAP
Specifies whether special characters such as < and & are replaced with the equivalent HTML entities (for example &lt; and &amp;).

O

OOSW
OO run-time switches.

R

RANDOM
If using SSL connections, externally generated random data that is stored as a numeric value in the RANDOM variable will be inserted into the initial salt value used to generate temporary key pairs used in SSL hand-shaking. The RANDOM value will only form part of the initial salt value and is an aid to generating more randomness and not an essential requirement.

S

SORTCOMPRESS
Tells the system whether or not to execute a compression routine on each record to be sorted.

Syntax

SET SORTCOMPRESS=5

Parameters

5 This is the only value that you can supply. It allows for run-length encoding of sort records, resulting in much better performance when records contain multiple repeated characters.

Comments

This variable is recommended if the sort records contain many single repeated characters, for example, multiple spaces, as it can be very effective in improving memory usage and therefore sort performance.

Example

SET SORTCOMPRESS=5
SORTSCHEME
Activates a sortscheme. Use in conjunction with SORTSPACE for improved performance.

Syntax

SET SORTSCHEME=1
Values
  • SORTSCHEME=1 - this is the only valid value for the environment variable. See SORTSPACE for more information.
SORTSPACE
The amount of memory to be allocated to internal workspace for SORT operations. This can be specified in different formats: for example, you could specify 64M, 2G, and 1000000 to give sort memory areas of 64 Megabytes, 2 Gigabytes and 1000000 bytes respectively.

Syntax

SET SORTSPACE=n[K|k|M|m|G|g]

Parameters

n[K|k|M|m|G|g The amount of memory to be allocated to internal workspace for SORT operations. K or k indicates kilobytes, M or m indicates megabytes and G or g indicates gigabytes. No letter indicates bytes. Defaults to 1 megabyte.

Comments

A larger value for SORTSPACE will generally result in a faster sort. However, if you specify a value that exceeds the capacity of main memory in your computer, such that the operating system has to page memory in and out, performance will be degraded.

Example

SET SORTSPACE=1024K

SORTTEMPSPACE
Specifies the amount of memory to be allocated to temporary workspace for SORT operations.

Syntax

SET SORTTEMPSPACE=n[K|k|M|m|G|g]

Parameters

n[K|k|M|m|G|g] The amount of memory to be allocated to temporary workspace for SORT operations. K or k indicates kilobytes, M or m indicates megabytes and G or g indicates gigabytes. No letter indicates bytes. 32 megabytes is the lowest amount of memory that can be allocated.

Comments

The memory allocation strategy used by SORT can be adjusted through use of SORTTEMPSPACE, which generally improves performance in systems suffering from memory fragmentation.

Example

SET SORTTEMPSPACE=250MB
SORTTYPE
Defines the sort type.

Syntax

SET SORTTYPE=2
Values
  • SORTTYPE=2 Forces SORT to use the file handler, so that format modifications are picked up from the extfh.cfg file.
  • Not setting this variable means that SORT will try to use CBL_ routines to read and write files to improve performance.
Note: 2 is the only valid value for this environment variable.
SSLDIR
If using SSL connections, this value specifies the generic location of the system's OpenSSL directory.

T

TXFILEP
The location of Micro Focus VSAM files.

X

XFHLOG
Determines the location of the log file when the LOG option is active.

Syntax:

SET XFHLOG=DEFAULT

Parameters:

DEFAULT - generates the log file in the current directory.

Comments:

If the XFHLOG variable is not set, the log file is created in C:\ProgramData\Micro Focus\Visual COBOL\[version-number] for .NET applications only. This variable has no effect for native applications; the log file is created in the current directory regardless.

The effect of this variable can be overridden by the LOGFILENAME configuration option.
