COBEC1240E <opt> required in OSVS for Length specification The <opt> option is required in OSVS COBOL programs to provide a length specification. Note that it is optional in VS COBOL II programs
since it can be defaulted to the LENGTH OF construct.
COBEC1242E MAP(literal) or FROM or MAPONLY is required On a SEND MAP command, a data area is required for the user data to be mapped when MAPONLY is not specified. This can be explicitly
specified using the FROM option or it can be implied if the argument for the MAP option is an alphanumeric literal.
COBEC1243W CSA option returns NULL - Non-portable usage The EXEC CICS ADDRESS CSA option will always return a null pointer/address value in the emulation. This option is a non-portable
usage due to its dependence on the specific format of internal CICS control blocks.
