All procedure statements
If a keyword parameter is to override the parameter or be added
to every EXEC statement in the procedure, code the parameter in the
usual way. For example, the ACCT parameter applies to all steps:
//STEP1 EXEC PROC=RPT,ACCT=5670
Note: A PARM parameter without a procstepname qualifier
applies only to the first procedure step. A TIME parameter without
a procstepname qualifier applies to the entire procedure and nullifies
any TIME parameters on procedure step EXEC statements.
If the keyword parameter is to nullify the parameter on every EXEC
statement in the procedure, code it without a value following the
equal sign. For example, the ACCT parameter is nullified in all steps:
//STEP2 EXEC PROC=RPT,ACCT=
