JCL

Standard:

Production JCL must be formatted according to specified guidelines.

Procedures:

Within each job, after the JOB statement, each job should include, in order, a JCLLIB statement, a JOBPARM statement, a PCROUTE statement, an OUTPUT statement for each user output format (if needed) and a comment briefly explaining the purpose of the job.

JCL statements should be aligned on columns 1, 12 and 18. If a parameter overflows beyond one of these columns, parameters should be neatly aligned.

Avoid unnecessary referbacks in JCL.

Set off all job/step purpose comments with a row of asterisks before and after.

Do not code REGION= if it is less than or equal to the system default.

Do not use the TAPEFILE utility.

JCL statements should be aligned on columns 1, 12 and 18. If a parameter overflows beyond one of these columns, parameters should be neatly aligned.

Avoid unnecessary referbacks in JCL.

The last statement in your JCL should be //.

• The JOB Statement
• The JCLLIB Statement
• The JOBPARM Statement
• The PCROUTE Statement
• The OUTPUT Statement
• Job Steps
• DD Statements
• Other

Notes:

Bin 36 is currently assigned to Production Control.

The batch security user for all production jobs is AUP00ZZ, except for internal support jobs (ISxxxx), which should use ISP14ZZ.

The current production procedure library is PCP40.PROC.CNTL.

The VER= parameter on the EASYIS, EASYPLUS and GO procs refers to the source for compiled executable user modules. The TBLVER= parameter refers to the appropriate table file. Both VER= and TBLVER= support parameters of TEST or PROD. The ACCOUNT= on EASYIS and EASYPLUS steps refers to the source Panvalet library.

Use UNIT=TAPE6250 to output to reel tapes. UNIT=TAPE will output to cartridge tapes.

On disk datasets, the optimal block size is the greatest multiple of the record length which is less than or equal to 6233.

On variable-blocked files, make the blocksize 6233. Do not use a tape for a temporary dataset if it is to be reused in the same step.

TAPES= refers to the maximum number of tape drives required in any given step (including previous step RETAINs).

The default region is 8192K.

The //PCROUTE statement is a form of the OUTPUT statement.
