CA JCLCheck Runtime Options › Description of Runtime Options › DEQUE

DEQUE

The DEQUE option issues a DEQ macro instruction to free selected data sets that are enqueued to CA JCLCheck (or to the job that invokes CA JCLCheck under CA Roscoe).

You can optionally request a list of the DEQ macro return codes, data set names, and so forth.

This option has the following format:

DEQue[(List|NOList)]|NODEQue

Default: NODEQue

• Use List to obtain a list of the DEQ macro return codes, data set names, and so forth. You normally use this feature only upon request of CA to assist in problem determination.
• CA JCLCheck must be linked as authorized and executed from an authorized library to use this feature.
• An alternate method is to run program CAZ2DEQ without options, but with the same DDs.
• This option is available for use in batch or under CA Roscoe, not under TSO.
• This option requires two additional JCL statements, which CA JCLCheck uses to bracket the JCL statements that describe the data sets to dequeue:

  //JCHKFREE DD DUMMY
  

  Code this statement as shown. It marks the beginning of the sequence of DD statements that describe the data sets to dequeue.

  /JENDFREE DD DUMMY
  

  Code this statement as shown. It marks the end of the sequence of DD statements to free.

Example: Free selected data sets

The following example dequeues the data sets allocated to SYSPROC and PROC01 and makes them available for use by other jobs on an exclusive basis (DISP=OLD).

    //JCLCHECK EXEC PGM=JCLCHECK,PARM=DEQ
    //SYSPRINT DD   SYSOUT=*
    //JCHKFREE DD   DUMMY marks start of DSNs to free

    //SYSPROC  DD   DSN=SYS1.PROCLIB,DISP=SHR
    //         DD   DSN=SYS2.PROCLIB,DISP=SHR
    //PROC01   DD   DSN=TEST.PROCLIB,DISP=SHR
    //JENDFREE DD   DUMMY marks end of dsn's to free
    //SYSTERM  DD   SYSOUT=*
