Significant Changes in Behavior or Usage

This section describes significant changes in behavior or usage in the current and past releases of . These changes could potentially affect the behavior of existing applications or impact the way the tools are used.

Note: This list does not include the changes in behavior introduced by any of the Patch Update releases. Refer to the Patch Update readmes for information about such changes.

.NET COBOL projects

The 9.0 release installs several .NET NuGet packages each of which contains the assemblies for a specific Micro Focus functionality. New .NET projects, as well as existing projects you edit or build in 9.0 are linked to a core package, MicroFocus.COBOL.Runtime.Core, that includes the basic functionality for the projects. You need to add any additional packages (such as a specific file handler, COBOL Accept/Display etc.) manually to the projects.

Building existing .NET COBOL projects created prior to 9.0 might result in build errors. You can ensure compatibility by enabling the use of the MicroFocus.COBOL.Runtime metapackage. Alternatively, you need to add any required NuGet packages manually to the older projects.

See Upgrading existing .NET COBOL project files for details.

Support for symbols files generated with previous versions of the product

Backward compatible support is provided for symbols files (.idy files) generated using any of the previous five major product releases.

When you attempt to debug, a version check of the .idy file is carried out, and if produced with a product version older than the last five releases, it is rejected and you are unable to debug with it. In such circumstances, recompile your application to generate a new .idy file. [5]

Licensing changes

  • The SafeNet Sentinel licensing system has been deprecated and will be not available in this product starting with the next major release - release 10.0. The SafeNet Sentinel licenses will not be supported after release 9.0. You can only use AutoPass licenses starting with release 10.0.

    You can replace your SafeNet Sentinel licenses with AutoPass licenses starting with release 8.0. However, it is not necessary to switch to AutoPass licenses unless you are adopting release 10.0. Contact Micro Focus Customer Care for further information.

Compiling C programs with the cob command

On AIX platforms, when using the cob command to compile C or C++ programs (for example, cob -xc filename.c) the compiler used is dependent on the version of the operating system: on AIX 7.2, an XL-based compiler is used; on AIX 7.3, a Clang-based compiler is used.

In a future release of the product (10.0 or later), only a Clang-based compiler will be supported, and any code compiled with the XL-based compiler will require recompilation. To prepare for this change if you plan to upgrade, you can run a script that scans for XL-compiled code, so you can see how much of an effect this change will have. The checkbin script is available from $COBDIR/bin: run checkbin -h for more details.

Default passing mode when passing pointers to a method

In previous releases, if a pointer was passed to a method without explicitly stating the passing mode (BY VALUE or BY REFERENCE), it was assumed to be passed BY REFERENCE. From this release, such items are assumed to be passed BY VALUE, making them consistent with other parameter types.

To pass a pointer BY REFERENCE, you must explicitly state reference in the method signature: for example:

method-id M1(reference ptr as pointer)
...

And ensure that the argument is also passed with the reference keyword; for example:

invoke M1(reference myptr)
...

Viewing active spool jobs

A new EXTFH configuration option, FLUSHSYSOUT, is now available to enable you to view the progress of active spool jobs. When set to ON (the default), the buffer is flushed after each record is written, enabling you to view the progress as it runs. Previously, a pre-defined buffer had to be completely written to before progress was displayed; this behavior was more performant, and so can be re-enabled by setting FLUSHSYSOUT=OFF [2]

Changes in Behavior in Release 8.0

Back to Top

For an up-to-date list of these changes for release 8.0, see this product's Release Notes available from the Product Documentation section of the Micro Focus Customer Care website.

Licensing requirements

The following platforms - Solaris, Red Hat on IBM Z System, SUSE on IBM Z System, and Ubuntu - are now licensed using a new licensing model called AutoPass. These platforms and licenses are not available from the Software Licenses and Download portal (sld.microfocus.com) if you are using the existing SafeNet license technology. To obtain AutoPass licenses for the aforementioned platforms, contact your account manager to discuss your actual requirements, and also raise a support incident to track the request.

Exceeding the maximum record length

The maximum record length supported by the File Handler is 62KB. If you create records that exceed this limit, a COBCH0649 error is generated on compilation. You can continue to use programs that utilise these large records, but you may experience adverse results in your file handling operations.

ISO2002 support via the Compiler directive

The ISO2002 directive now supports an option to provide different levels of ISO2002 features. ISO2002"1" provides the level of features supported in Server Express and Net Express, and ISO2002"2" provides those features, plus additional ones added since Visual COBOL. If you have used the ISO2002 directive in Server Express/Net Express, and are migrating to Visual COBOL, use ISO2002"1" if your applications are affected by the change in behaviors provided with ISO2002"2".

Initializing variable-length groups when ODOSLIDE is in effect

The target of an INITIALIZE statement cannot be a variable-length group if the ODOSLIDE Compiler directive is set. This now results in a severe syntax error, whereas in previous releases this was incorrectly allowed to compile and produced unexpected run-time results.

Producing a stackdump

Stackdump production is now only available on Linux platforms (both 32- and 64-bit, where supported). Previous availability on Solaris platforms is no longer supported.

Reverse Debug and Live Recording

Reverse Debug and Live Recording functionality is licensed and installed separately from undo.

io. You can enable reverse debug functionality by downloading the extension from the Micro Focus Marketplace.

JVM COBOL interoperating with other languages

JVM COBOL programs compiled with REENTRANT"2" now produce instance methods, whereas previously, compilation of these programs produced static methods. If your non-COBOL code relies on these methods being static, you will have to refactor your code to handle this.

Compiling C programs with the cob command

On AIX platforms, when using the cob command to compile C or C++ programs (for example, cob -xc filename.c) the compiler used is dependent on the version of the operating system: on AIX 7.2, an XL-based compiler is used; on AIX 7.3, a Clang-based compiler is used.

Early warning of compatibility issues with current operating systems

In order to better support modern operating systems, we are aligning closely with their operability guidelines. We now detect previously-undefined behavior when interacting with OS level functions.

Error RTS096 alerts you to any calls to the operating system's fork() API, in a process that has directly or indirectly called COBOL functionality, in your code.

The error gives you an early diagnosis of a situation which, if left unchecked on modern operating systems, could lead to deadlocks, crashes or other failures at run time. These problems would often occur intermittently and be very challenging to track down.

See the KB article https://community.microfocus.com/t5/Visual-COBOL-Knowledge-Base/fork-rts64-Error-96-encountered-in-child-process/ta-p/1771191 for more details.

Call prototyping in library routines

The copybooks cbltypes.cpy and cblproto.cpy, provided by this system for call prototyping in library routines, include features of the latest syntax, specifically the CONSTANT keyword. If these files are used in conjunction with the MF directive, it should be set to the current level, 21; otherwise, you should remove the directive, or do not use these copybooks.

Database Access - OpenESQL

Just like other DBMS SQL COBOL precompilers, OpenESQL now follows embedded SQL standards and disallows the use of group host variables in WHERE <column> = :hostvar clauses. In the past, this was not flagged at compile-time, and would lead to unpredictable results when executed.

National data items in JVM COBOL code

JVM COBOL code that uses IS NUMERIC tests on NATIONAL or NATIONAL NUMERIC data items, or uses NATIONAL NUMERIC data items in programs compiled with the CHECKNUM Compiler directive must be recompiled in this release. Compiled code from earlier products that uses such constructs will generate a MissingMethodException error when run under this release.

VALUE clause not permitted to follow items that use the OCCURS DEPENDING ON clause when ODOSLIDE in effect

If your Working Storage contains a data item with the OCCURS DEPENDING ON phrase, and ODOSLIDE is in effect, any subsequent data items at the same or higher level must not contain a VALUE clause. If they do, an error (COBCH1962) is now generated.

If you cannot remove the VALUE clauses from your source code or remove ODOSLIDE, contact Customer Care.

Changes in Behavior in Release 5.0

Back to Top

For an up-to-date list of these changes for release 5.0, see this product's Release Notes available from the Product Documentation section of the Micro Focus Customer Care website.

Communications Facility syntax no longer supported

The Communications Facility (also referred to as the COMMS SECTION or COMMUNICATION SECTION) has long since been deprecated. Certain syntax relating to this was still accepted (but ignored) by the Compiler. That syntax is no longer permitted, and if encountered, the Compiler will now generate an error (COBCH1895 Communication Facility not supported); you must remove the section from your sources before recompiling.

Calling coblongjmp() within an error procedure, exit procedure or signal handler

Calling coblongjmp() within an error procedure, exit procedure or signal handler now generates a fatal Run-Time System error message: COBRT131 coblongjmp() can not return from current context (Fatal).

This scenario was previously documented as a restriction, and is now enforced, to prevent subsequent issues. The resolution to such an error is to refactor the code to remove the coblongjmp() call from any error procedures, exit procedures, or signal handlers.

Changes in Behavior in Release 4.0

Back to Top

For an up-to-date list of these changes for release 4.0, see this product's Release Notes available from the Product Documentation section of the Micro Focus Customer Care website.

The numbers that follow each issue are the Support Incident Numbers followed by the Reported Problem Incident (RPI) number (in parentheses).

Enterprise Server security

Web access to the Enterprise Server Console Log and Communications Server Log is now restricted when the enterprise server region is secured using external security. Users will be required to provide a valid username and password in order to view either log file.

Web access to the logs can be controlled using the standard ACL definitions under the new Communications Server resource class, with resources Enterprise Server Console Log and Communications Server Log. If these resources exist, users require 'read' access to be allowed to view the logs. If the resources do not exist, the default behavior is to allow 'read' access on entry of a valid username and password.

An example of the new resource class and resource definitions can be found in the es_default_ldap_unix.ldf file, which is located in the etc sub-directory of your product directory.

Application Server JCA Support for Enterprise Server

With this release, all CICS-related Java artifacts have been delivered using a new directory structure under the javaee-ccl directory of your installation directory. The javaee-ccl directory structure mimics the structure of the javaee directory. For example, mfccl.jar is no longer located in the bin subdirectory, but can be found in the javaee-ccl\common directory.

Test Coverage results

Schema changes that affect the test coverage results generated from the tcutil utility mean that if you propagate the results to a third-party application (for example, an XSLT processor), and rely on the <copyFileCoverage> element, you need to alter your transformations to focus on <sourceFileCoverage> instead. The element was renamed to more appropriately reflect its contents, as tcutil now gives global coverage for all source files (not just copybooks).

Changes in Behavior in Release 3.0

Back to Top

For an up-to-date list of these changes for release 3.0, see this product's Release Notes available from the Product Documentation section of the Micro Focus Customer Care website.

The numbers that follow each issue are the Support Incident Numbers followed by the Reported Problem Incident (RPI) number (in parentheses).

Compiler Directives

The default for the FASTINIT directive has changed: FASTINIT is now the default when setting the MF dialect. The directive remains not set by default (that is, NOFASTINIT) for other dialects.

OpenESQL

Back to the list

The new OpenESQL OPTIMIZECURSORS SQL compiler directive option is turned on by default for ODBC (DBMAN=ODBC). This ensures that embedded SQL cursors that use WITH HOLD and FOR UPDATE clauses have the same data integrity across all databases.

If your applications require the OpenESQL preprocessor to use the behavior provided in an earlier release, compile them using OPTIMIZECURSORS=NO.

Reserved words

Back to the list

  • There have been a number of new reserved words added to the COBOL language; these are all in effect under MFLEVEL"19", which is the default level when running under the MF dialect. Any of the following words are now not allowed under default conditions, and you will need to remove/rename them, or specifically configure your environment to allow them:
    • ALLOCATE
    • FREE
    • JSON
    • END-JSON

    See Reserved Words Table at the end of this topic for more information.

Changes in Behavior in Release 2.3 Update 2

Back to Top

This section describes significant changes in behavior or usage. These changes could potentially affect the behavior of existing applications or impact the way the tools are used.

The numbers that follow each issue are the Support Incident Numbers followed by the Reported Problem Incident (RPI) number (in parentheses).

Enterprise Server

Back to the list

  • Previously, it was possible to install groups that should not have been installed. If a group name, as defined in the Startup List, did not exist in the list of Groups then the next Group in the alphabetical order would be loaded instead. Now, if a Group is not defined in the list of Groups, a warning that the Group could not be loaded is issued.

    2869848 (619107)

  • On UNIX, if the "File Path" setting was not specified in the configuration of an Enterprise Server, the environment variable TXFILEP was defaulting to $COBDIR/etc/cas. This has been changed and TXFILEP is not populated when the "File Path" is not specified.

Micro Focus Directory Server

Back to the list

  • The "-n" option for the mfds command now supports hostnames as the network addresses in addition to IPv4 addresses.

    2816871 (1099564)

Monitoring and Management

Back to the list

  • Messages that are written to the console log by applications that perform "display upon console" now contain a standard message ID (CASMG0001I).

    2854207 (1103659)

Run-Time System

Back to the list

  • The command_line_linkage tunable has been deprecated; equivalent functionality can be achieved by using the COMMAND-LINE-LINKAGE Compiler directive instead.

    2838118 (1101539)

    Attention: As of release 4.0, this tunable is no longer deprecated.

Changes in Behavior in Release 2.3 Update 1

Back to Top

This section describes significant changes in behavior or usage. These changes could potentially affect the behavior of existing applications or impact the way the tools are used.

The numbers that follow each issue are the Support Incident Numbers followed by the Reported Problem Incident (RPI) number (in parentheses).

Run-Time System

Back to the list

  • The Audit Manager contains a new TIMEOUT option. When a client sends an audit event using the ‘CBL_AUDIT_EVENT’ API, the event gets placed in the next available slot in a shared memory block. If shared memory is full (i.e. no slots are available), the event is re-tried until a slot becomes available.

    If no Audit Manager is running, no events are removed from shared memory, and no slots will ever become available. Therefore, use the new TIMEOUT option so that a client will only retry sending until the TIMEOUT duration is reached; after which, it will stop sending audit events. If Audit Manager is recycled, events will start to be sent again.

    To set the TIMEOUT for all Audit Manager clients, specify the following line in the Audit Manager configuration file:
    mfaudit.timeout = n
    Where n is the timeout value in milliseconds.

    To set the TIMEOUT for an individual Audit Manager client, use the ‘CBL_AUDIT_CONFIG_PROPERTY_SET’ API. It takes an integer property-value, which should be the timeout value in milliseconds.

    If TIMEOUT is set using both methods, the client property TIMEOUT takes precedence, unless this property is set to zero; in such cases, the TIMEOUT in the configuration file is used. If you use the ‘CBL_AUDIT_CONFIG_PROPERTY_GET’ API on the ‘TIMEOUT’ property, it only returns the TIMEOUT value for the client property; it does not return the value set in the configuration file.

    2838689 (1101685)

  • Several changes have been made to the implementation of IS DBCS, IS KANJI and IS JAPANESE class condition tests:
    • IS [NOT] DBCS

      When CHARSET"EBCDIC" is in effect, the IS DBCS test returns true when each character in the string is deemed to be a valid DBCS character. A valid character has its first byte in the range 0x41 through 0xFE, and the second byte in the range 0x41 through 0xFE, or the character is an EBCDIC space (0x4040). When CHARSET"ASCII" is in effect, the DBCS test uses an OS call to determine if the string contains only valid double-byte character, and returns true if valid.

    • IS [NOT] KANJI

      When CHARSET"EBCDIC" is in effect, the IS KANJI test returns true when each character in the string is deemed to be a valid Kanji character. A valid character has its first byte in the range 0x41 through 0x7F, and the second byte in the range 0x41 through 0xFE, or the character is an EBCDIC space (0x4040). When CHARSET"ASCII" is in effect, the IS KANJI test uses an OS call to determine if the string contains only valid Kanji character, and returns true if valid.

    • IS [NOT] JAPANESE

      When CHARSET"EBCDIC" is in effect, the IS JAPANESE test is not supported, and will generate a COBCH1806 Feature not supported in selected charset message on compilation.

      When CHARSET"ASCII" is in effect, the IS JAPANESE test returns true when the string contains only double-byte Japanese characters or single-byte Japanese Katakana characters, and returns true if valid. When NSYMBOL"NATIONAL" is in effect, these class tests are not supported, and will generate a COBCH0303 Operand has wrong data-type message on compilation.

    2812895 (1098401)

SQL Option for DB2

Back to the list

  • Spurious errors were sometimes returned while querying using an ALIAS.

    2830383 (1100609)

Changes in Behavior in Release 2.3

Back to Top

This section describes significant changes in behavior or usage. These changes could potentially affect the behavior of existing applications or impact the way the tools are used.

Where present, the numbers that follow each issue are the Support Incident Numbers followed by the Reported Problem Incident (RPI) number (in parentheses).

CAS Security

Back to the list

  • The Enterprise Server External Security Facility now includes MLDAP ESM Module 2.0, with a new algorithm for identifying the best-matching resource-access rule and ACE for resource-access security checks. This algorithm is faster and matches most customers' expectations. The new algorithm also provides an optional "username substitution" feature. It can be enabled by setting "rule substitutions" to "yes" in the [Operation] section in the Security Manager configuration text area. When this is enabled, the string "${user}" in a resource-rule name will be replaced with the name of the user that makes the request. For example, a DATASET rule named "USERS.${user}.**" would apply to datasets with the requesting user's name as the second qualifier. In rare cases, customers with complex, ambiguous resource-access security rules might see experience changes in behavior as a result of the new algorithm. The old algorithm is still supported and can be enabled by setting "version 1 authentication" to "yes" in the [Operation] section of the Security Manager configuration.

    2807531 (1097783)

CAS XA Switch modules

Back to the list

  • The XA switch modules now support dynamic registration.

    2682101 (1092325)

  • The XA switch modules now support batch-only operations when multiple XA Resource Managers have been defined.

    2664675 (1091082)

  • In Visual COBOL 2.2 update 2, Micro Focus identified undefined run-time behavior when the following combination of directives was specified: SIGN"EBCDIC", CHARSET"ASCII", and one of the following: HOST-NUMMOVE, HOST-NUMCOMPARE or SIGN-FIXUP. Previously (Visual COBOL 2.2 update 1 and earlier), if this combination was specified, the SIGN”EBCDIC” directive should have been ignored, to avoid a mixture of ASCII and EBCDIC characters; however, SIGN”EBCDIC” was still being honored, resulting in undefined run-time behavior. Therefore, this combination of directives is now invalid for Visual COBOL 2.2 update 2 or later, and if specified, will be rejected at compile time.

    2786397 (1095265)

File Handling

Back to the list

  • Custom file handlers (using DYNREDIR) are now called for each part of a concatenated file.

    2795077 (1096322)

File Locking

Back to the list

  • In versions prior to Visual COBOL 2.3, the semantics of the sharing phrase specified in an OPEN statement or used within a call to CBL_OPEN_FILE were not correctly applied in some cases on UNIX and Linux platforms. From version 2.3 onwards, the sharing phrase is correctly honored when the tunable strict_file_locking=true is set, which is the default setting.

    Example of potential changes in behavior:

    • Process-A opens a file with read-only access and a sharing mode that denies other processes write access (SHARING WITH READ ONLY).
    • Process-B then attempts to open the file with read-only access and a sharing mode that denies other processes read access (SHARING WITH NO OTHER).

    With strict_file_locking=true, Process-B is unable to open the file, because Process-A has successfully opened the file allowing only read access.

    With strict_file_locking=false, Process-B successfully opens the file.

    If your application encounters unexpected OPEN conditions or fails to open files, it might be as a result of the new file locking behavior. In such circumstances, we recommend that you review the file locking and sharing requirements of your application and refactor your source code to work with the default setting. The original file locking and sharing behavior can be restored by setting strict_file_locking=false.

J2EE Connector

Back to the list

  • This release provides a new command-line argument to Java, mf.ssl.algorithm, which can be set to an appropriate algorithm.

    2799213 (1096684)

MF Server Administrator (GUI)

Back to the list

  • Passwords that entered through either the MFDS or the ESMAC interface now use the same encoding.

    2792382 (1096011)

Updated Run-Time System

Back to the list

  • COBOL Server now provides an execution environment capable of running applications that were each built using different development products. A consequence of this is that if your application has a main COBOL executable (.exe) that was built with a version of Visual COBOL prior to version 2.3, you should ensure that the executable is rebuilt and packaged with the new run-time system. You can rebuild from the IDE or the command line.

    Other COBOL subprograms built with previous versions of Visual COBOL are not required to be rebuilt.

The numbers that follow each issue are the Support Incident Numbers followed by the Reported Problem Incident (RPI) number (in parentheses).

Compiler

Back to the list

  • When using the HOSTRW directive with the mainframe dialect, Report Writer will now produce the full range of ASA control characters and will emulate mainframe print files.

    2697615 (1094527)

  • Fixed Binary (p<=7) is now an 8-bit, signed, 2's complement binary integer by default.

Documentation

Back to the list

  • The default setting for the MFALLOC_PCFILE environment variable has changed; the default is now set to Y, which means that when cataloguing a file that has a DCB attribute of DSORG=PS, a physical file is created for it if one does not exist. Previously, the default was set to N, which meant that a file was not created.

    2697571 (1094370)

Enterprise Server

Back to the list

  • The Enterprise Server External Security Facility now includes MLDAP ESM Module 2.0, with a new algorithm for identifying the best-matching resource-access rule and ACE for resource-access security checks. This algorithm is faster and matches most customers' expectations.

    The new algorithm also provides an optional "username substitution" feature.

MF Directory Server

Back to the list

  • The mfds command line option for exporting registered Enterprise Server definitions to an XML file now supports the "*" option. This exports all registered servers rather than a specified server. Multiple server definitions are now exported into the target directory and saved into a file with the default name ALLSERVERS.xml. The import option now also supports the import of multiple server definitions from a single XML file.

    2641890 (1088838)

  • mdump now supports a new option, -e, to help you query the Security Manager configuration details. The possible values of the option are: "1" - shows security configuration that applies to any returned enterprise servers; "2" - shows security configuration for MFDS and the default Enterprise Server security configuration. This requires MFDS version 1.15.00 or higher; "3" - returns the properties of all configured external Security Managers.

    2487164 (1081693)

MF Server Administrator (GUI)

Back to the list

  • When adding a user to an external security manager, you can now include a password expiry time in the Advanced Configuration section of the Add New User wizard in Enterprise Server Administration. The field value is specified using generalized time format (YYYYMMDDHHMMSS.0Z), and can be used by the MLDAP ESM for calculating whether a user's password has expired and requires updating. This value may only be specified using this page when adding a user. You need to use an external directory services configuration tool to edit it.

    2562118 (1083203)

Request Handler

Back to the list

  • A problem that caused BIS to create log files in a directory named C:\ProgramData\AcuCorp\BIS\LogFiles was fixed. BIS no longer creates log files unless specified and the BIS logging service is now disabled by default. To enable it, you need to use the following global environment variable: BIS_LOG=[ OFF | ON | <directory> ] Where the values are:
    • OFF - disables logging (the same as if BIS_LOG is not specified or is left blank)
    • ON - enables logging and directs the log files into the default location, which must not be read-only.
    • <directory> - enables logging and directs the log files into the specified directory. The user must ensure that the BIS request handler has write rights for this directory. The directory must be an absolute path or network path. If the specified directory does not exist, BIS will attempt to create it. The containing directory must exist.

    The BIS_LOG variable is only examined when the BIS application pool is started or recycled. After setting or changing BIS_LOG, IIS must be restarted in order for the variable to take effect.

Enterprise Server

Back to the list

  • HSF includes the following enhancements:
    • A new record type (JCLF) for JCL files.
    • A Job class has been added to the JCL JOBSTART records.
    • A condition code has been added to the JCL STEP records.
    • Statistics for up to 5 Transient Data Queues per CICS record has been added (same as for exisiting TSQ stats). The HSF files will now be created with the following header: #HSFVer=02 Type,PID,Task,Date,Time,Tran/Job,User/DDName/CC,LU/Step,Prog/DSName,Latent/ReadCount,Resp/WriteCount,API/RewriteCount,SQL/DeleteCount,IMS,DSType,DSAccessType,File1,Count1,Time1,File2,Count2,Time2,File3,Count3,Time3,File4,Count4,Time4,File5,Count5,Time5,TS1,Count1,Time1,TS2,Count2,Time2,TS3,Count3,Time3,TS4,Count4,Time4,TS5,Count5,Time5,TD1,Count1,Time1,TD2,Count2,Time2,TD3,Count3,Time3,TD4,Count4,Time4,TD5,Count5,Time5

    2552658 (1082755)

OpenESQL

Back to the list

  • SQLWARN4 flag was not being set when more than one row was returned for a singleton SELECT statement. The OpenESQL run-time now correctly sets SQLWARN flags when a singleton SELECT statement returns multiple rows.

Run-Time System

Back to the list

  • When running a full-screen application inside a terminal emulator on Linux, the actual size of the terminal is read at startup and reread when the terminal is resized.
