CA JCLCheck Runtime Options › Description of Runtime Options › PREFIX

PREFIX

The PREFIX option specifies the ddname prefix that is used for the dynamic allocation in non-z/OS systems and for JES3 //*MAIN statement CA PROCLIB support.

This option has the following format:

PREfix[(SYSDD)|(character-string)]|NOPRefix

SYSDD|character string is the name of the dynamic allocation prefix.

• Dynamic allocation is required to allocate any of the following:
  • Control statement data sets for the CTLSCAN option.
  • Procedure libraries for the EASYPROC option.
  • Program and source libraries for the PXREF option.
• For non-z/OS dynamic allocation to succeed, specify a DD statement with a ddname beginning with the specified PREFIX character-string in the CA JCLCheck JCL that allocates the volume containing the library. In practice, it is best to provide such a DD statement for every resident and reserved volume in the installation.
• CA JCLCheck uses SYSDD as the non-z/OS dynamic allocation prefix, when you do not specify this option or if you omit the PREFIX character-string operand.

You can also use this option with JES3 //*MAIN ALT PROCLIB support. PRE(DYNAL) causes CA JCLCheck to look for DD statements with names that begin with the characters DYNAL, rather than SYSDD, when performing necessary dynamic allocation.
