If I understand what you are trying to say, consider this. Suppose you have some JCL like this: //TESTPROC PROC UNIT=SYSDA //SETP1 EXEC PGM=IEFBR14 //DD1 DD DISP=(NEW,DELETE),UNIT=&UNIT,SPACE=(TRK,1) // PEND By your logic, if you code // EXEC PROC=TESTPROC,UNIT=BANANA "BANANA" does not override SYSDA for the unit because it causes a JCL error. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
