IGGCSIRX is a REXX EXEC that uses CSI. Move this EXEC to a REXX EXEC library and ensure that the linkage library for IGGCSI00 is accessible by the TSO session. IGGCSIVS will run with any release of DFSMS supported by CSI.

When executed, IGGCSIRX will prompt the user for a filter key. This should be a partially qualified data set name as described for the selection criteria field CSIFILTK. The data set name, its type, and volume serial number(s) are returned to the user's TSO session.
