Making the INQUIRE PROGRAM command threadsave would also help the IBM DEBUG product! The IBM DEBUG product is active in virtually all of my shop's test regions. Every time an application program does an EXEC CICS LINK to a program, IBM DEBUG gets invoked and issues an EXEC CICS INQUIRE PROGRAM command. Since this cmd is not threadsave, the task is frequently forced from the L8 to the QR mvs tcb. This wastes some cpu. but more important, this impacts me when I am doing analysis on what vendor programs I can/should mark as threadsafe, or required, to prevent tcb mode switches. With IBM DEBUG's repeated use of the EXEC CICS INQUIRE PROGRAM cmd, the number of tcb mode changes can be drastically different in a cics region running IBM DEBUG than in a prod region where we do not run IBM DEBUG. Making the INQUIRE PROGRAM cmd threadsave would eliminate this difference. Also, my shop also runs a vendor application that does an EXEC CICS INQUIRE PROGRAM once within every program it executes to obtain the address of a load module(which is used as a table of values). All other commands executed by this application are threadsafe. Making INQUIRE PROGRAM cmd threadsave would permit me to run this application's tasks/pgms completely on an L8 mvs tcb. I have asked the vendor to change the EXEC CICS INQUIRE PROGRAM to EXEC CICS LOAD PROGRAM to obtain threadsafe processing. But I do not know if they are going to make the change.
