Under the topic "Overrides" for the REGION parameter in the job card in the JCL Reference, I see this: <quote> A JOB statement REGION parameter applies to all steps of the job and overrides any EXEC statement REGION parameters. Code EXEC statement REGION parameters when each job step requires a different region size. The system uses an EXEC statement REGION parameter only when no REGION parameter is on the JOB statement and only during the job step. </quote> Similarly, under "Overrides" for the REGION parameter on the EXEC card, <quote> A JOB statement REGION parameter applies to all steps of the job and overrides any EXEC statement REGION parameters. When no REGION parameter is on the JOB statement, the system uses an EXEC statement REGION parameter, but only during the job step. Code EXEC statement REGION parameters when you want to specify a different region size for each job step. </quote> Looks clear to me. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
