Using a percent sign in partially qualified data set names

The percent sign, %, acts as a place holder for a single character during data set name filtering.

The rules for using % in a qualifier are:

Each % corresponds to exactly one character.
% can be specified more than once, consecutively or in any level of the qualifier.
A % cannot match a null ('') or a period ('.').
Use of a % in filtering does not change any of the other filtering specifications for data set names.

Consequently, specifying I%M.A.%AT%%ET matches the data set names IAM.A.DATASET and IBM.A.BATTYET, but not IAM.A.DATASE, IAM.AA.DATASET, IAM.A.ATASET, or IM.A.DATASET.
