I considered that. But the PROCLIB is resolved at JCL read time, not at execution time. So if I submit the JCL on Prod (where CA-7 runs), it uses the Prod version of the PROC. Even if the job is SYSAFF'd to run on Development. This method would work if Prod and Development ran the identical versions at all times. And would save JCL changes for a simple case. But the simple use of an ALIAS would do the same. The desire is to use the correct DSN dependant on the running system at the time of execution. Without any JCL change needed. If fact, to have it run with the system-dependant DSN even if the job's SYSAFF is changed dynamically. In program terms: "Late Binding" or "Dynamic Binding" where the DSN name is not resolved until the last possible instant. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
