    ** ASMA057E Undefined operation code

Local fix

  • You need to add the NOCOMPAT to your ASM step in your JCL to
    make it work.
    
    So in this step here:
    
    //ASM      EXEC PGM=&ASMBLR,
    //         PARM='SYSPARM(INITIAL),DECK,NOOBJECT,ALIGN',
    //         REGION=&REG,
    //         COND=(3,LT,ASSEM)
    
    You need to change it to the following:
    
    //ASM      EXEC PGM=&ASMBLR,
    //         PARM='SYSPARM(INITIAL),DECK,NOCOMPAT,NOOBJECT,ALIGN',
    //         REGION=&REG,
    //         COND=(3,LT,ASSEM)

    * USERS AFFECTED: All CICS users                               *
    ****************************************************************
    * PROBLEM DESCRIPTION: Assembling a DFHSIT with the            *
    *                      COMPAT(CASE) option results in ASMA057E *
    *                      messages and the job fails with         *
    *                      RC=0012.                                *
    ****************************************************************
    Lower case constants and equates introduced in CICS TS 6.2 to
    the DFHSIT macro cause the assembly of DFHSIT, when the
    COMPAT(CASE) option is used, to fail.
    

Problem conclusion

  • The lower case constants and equates in the DFHSIT macro have
    been changed to upper case.
