In the Filter section, to initially filter the data sets that are retrieved, in the
DSN Filter field, type a data set name filter (for example: MFIJCL.*.*.DATA).

Note: To further control filter behavior, use
Disable Additional Qualifiers.
Use this option to make catalog searching and filtering more consistent with the results produced on the mainframe. Check
the option to disable the use of additional qualifiers when filtering the catalog results. For example, when checked, a filter
of A.B would only return a data set of A.B. This option emulates the effect of disabling the 'Include Additional Qualifiers'
option on the mainframe. When unchecked, a filter of A.B would return all data sets starting A.B (as if A.B** had been entered).
