The SMP/E REPORT MISSINGFIX command helps determine whether fixes exist that are applicable but have not yet been installed. We recommend using the SMP/E REPORT MISSINGFIX command with the FIXCAT keyword for COBOL V5.1 which is: IBM.TargetSystem-RequiredService.Enterprise-COBOL.V5R1 The command to use to find all of the service required to use COBOL V5.1 or run programs created with COBOL V5.1 is: SET BDY(GLOBAL). REPORT MISSINGFIX ZONES(URZONE1,URZONE2) FIXCAT(... [More]
With COBOL for z/OS, V5.1, you can use the AFP option to control the compiler usage of the Additional Floating Point (AFP) registers that are provided by z/Architecture processors. The syntax is as follows: --VOLATILE--. >>-AFP(-+-NOVOLATILE-+-)---------------------->< The default is AFP(VOLATILE). The Enterprise COBOL compiler generates code that uses the full complement of 16 floating point... [More]
Standard COBOL 85 requires that program-name be specified as a user-defined word. IBM COBOL compilers extends the standard rule and allow program-name to be a user-defined word or alphanumeric literal, but not a figurative constant, that identifies your program. It must follow the following rules of formation, depending on the setting of the PGMNAME compiler option: PGMNAME(COMPAT) If program-name is an alphanumeric literal, the rules for the name are the same except that the extension characters $, #, and @ can be included in the name of the...

With COBOL for z/OS, V5.1, you can use the ARCH option to specify the machine architecture for which your executable program instructions are to be generated. The syntax is ARCH( n ). Parameter n is an integer between 6 and 10 inclusive, specifying the machine architecture for which instructions are to be generated. ARCH(6) is default. If you specify a higher ARCH level, the compiler generates code that uses newer and faster instructions. Your application might abend if it runs on a processor with an architecture level lower than what you... [More]
End markers are a combination of words followed by a separator period that indicates the end of a COBOL program, method, class, factory, or object definition. The following end marks are IBM extensions for both AIX and Enterprise. Please pay attention to the conventions when you use them: For programs - program-name must be identical to the program-name of the corresponding PROGRAM-ID paragraph. Every COBOL program, except an outermost program that contains no nested programs and is not followed by another batch program, must end with an END... [More]
Enterprise COBOL Developer Trial for z/OS, V5.1 is now available. The Trial lets you assess the value that could be gained from migrating to Enterprise COBOL for z/OS , V5.1, before making a formal, upgrade decision. This trial enables the evaluation of the latest IBM COBOL capabilities, in a non-production environment, without the prerequisite time and resources commitments required for a full, production migration project.
