Search for the active rule containers

The search for the user-specific and pubset-global rule containers involves two stages:

Stage 1:	Search for user-specific rule containers
	The rule container SYS.UDF or SYS.UDJ is searched for under the catalog and user ID of the file or job variable for which the default values are to be searched. If such a rule container exists then a check is performed to determine whether it or one of its follow-up containers contains a matching rule. If it does, the search is terminated and the rule is evaluated.
Stage 2:	Search for pubset-global rule containers
	If stage 1 of the search does not locate a matching rule, then a pubset-global rule container $TSOS.SYS.PDF or $TSOS.SYS.PDJ is searched for under the same catid. If such a container (and any associated follow-up containers) exists, a search is performed for a matching rule. If such a rule is located, the search is terminated.

If the second stage of the search fails to yield a result; the usual system default values are used.
