ISRSUPC - Clarifications

Postby Viswanathchandru » Sun Oct 21, 2012 7:41 pm

Dear all,

Just want to know in which language ISRSUPC PGM was written. Ofcourse, I tried google but i didn't find much information on that. Apologize if my thoughts are wrong!

why post to the cobol forum ???
ISRSUPC is not certainly written in COBOL

running an AMBLIST on the load module will tell
to save You the stress of the research here is the jcl snippet to use
 000005 //IDR     EXEC PGM=AMBLIST
 000008 //SYSIN     DD *

PLX-390 is then IBM IUO language and compiler used for system related programming
When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,
so that I am sure that the information requested can be reached with a very small effort

To expand Mr. Sorichetti's post a little.

PLX-390 is an IBM Internal Use Only language. It is known to be similar to PL/I, but with changes to make it more usable for systems work.

As an addition, the original PC DOS and OS/2 version ware, if I remember correctly, written in x86 assembler, the later Windows (DLSupCxx) versions were written in Delphi. All versions (PC & z/OS) were originally written by the late Donald Ludlow.
