CA JCLCheck Calling Parameter List

You can call, link, or attach to CA JCLCheck using one to four of the following four parameters:

Parameter 1

Specifies CA JCLCheck runtime options.

This parameter is in standard z/OS calling parameter format: a halfword length field, followed by the option keyword, separated by commas or blanks. This parameter cannot be longer than 100 characters. The length value in the halfword length field is that of the character data and does not include the halfword itself.

Parameter 2

Specifies alternate ddnames.

This parameter is a 50-byte field in the following format:

bytes 0-1    length of the list ( DC H'50' )
bytes 2-9    SYSIN alternate ddname
bytes 10-17  SYSPRINT alternate ddname
bytes 18-25  SYSPROC alternate ddname
bytes 26-33  SYSRDR alternate ddname
bytes 34-41  SYSTERM alternate ddname
bytes 42-49  prefix for non-z/OS allocation

Note: If you do not want to override a default ddname, specify hex zeros in the respective alternate ddname entry in this list.

You can provide an exit routine for the SYSIN, SYSPRINT, and SYSTERM files. The first word (four bytes) of the respective ddname entry in the list above stores the entry point address of the exit routine.

Parameter 3

Specifies the addresses of an alternate set of CA JCLCheck standard exit routines.

The addresses passed in this 32-byte list are the respective entry points for the CAZ1XJOB, CAZ1XEXE, CAZ1XDD, CAZ1XSTE, CAZ1XERR, CAZ1XEOJ, CAZ1XEOF, and CAZ1XCTL exit routines. If you use the exit routines linked with CA JCLCheck, make this parameter zero. If this parameter is supplied, CA JCLCheck ignores any exit routines linked with it.

Optionally, you can supply an address pointer in the list of eight exit addresses or code a fullword X'FFFFFFFF' to indicate that any exits linked into CA JCLCheck will remain active.

Parameter 4

Specifies an initial value of one fullword for the field $USER in the $JCLGLBL area.

The $JCLGLBL area is addressable using R12 through CA JCLCheck. Use this parameter to pass an address constant, perhaps the address of a work area in the calling program, that is available to any standard or I/O exit. If you select the INTSUR option, the initialization of all four user words, you must make this parameter four fullwords in length.

CA JCLCheck moves these four fullwords to the fields $USER through $USER4 in the $JCLGLBL area.
