Re: TFRGRPJOB vs ACTGRP

[Dave <dfx1@xxxxxxxxxxxxxx>]

Thanks Gary,
The program running with library list libl1 shows a subfile, an option on
the subfile runs another application that must use identically named files
residing in different libraries so uses library list libl2. In your step 3,
the called program will use any files that are already open in libl1.
