How to find a member in list of datasets

If you want to find a member but you don’t know the PDS to which it belongs and you only know the High level qualifier of the PDS.

For example: Let’s consider High level qualifier as RF01.pp258c.* and member as RG57TDLT.

1. Go to 3.4 and list all PDS with  RF01.pp258c.*
2. Now issue, MEMBER RG57TDLT on the command line.
