Tom Marchant's append was right on target. All the other appends on this subject that showed up in my "digest" were off base. It certainly is quite "possible" to delete data sets and bypass system protections. However, it is not proper, appropriate, or supported to delete a data set that is in an active LNKLST set.
If you want to break your own system, that is your business, but please do not expect sympathy. Use of SETPROG LNKLST UPDATE is unquantifiably risky. It might, or might not, be better than re-IPLing. There is no way of knowing. The choice of risk is yours. Use of SETPROG LNKLST UNALLOCATE is provided to allow you to deal with an uncataloged data set of the same name as a data set in an active LNKLST set.
