If you want to capture and analyze the results of an IPCS subcommand like WHERE or SYSTRACE, the traditional answer is the one suggested by Don Poitras. (1) Allocate a print file. If you're writing the EXEC to support others who may use ddname IPCSPRNT for their own purposes, use another ddname and employ the CLOSE and OPEN subcommands to identify that ddname as a target. (2) Have the subcommand write its output there. (3) Close the print file. Reopen IPCSPRNT, positioned to the end, if the EXEC preempted the print file destination. (4) Use REXX to read through the output. If you're planning to be running z/OS V1R7 soon, look at whether the REPORT primary command that the release introduces is a reasonable substitute. REPORT has a number of capabilities, one of which is to look at lines in a report, e.g. SYSTRACE, that has been captured by IPCS. Another ability is to format a newer report that would be nested in front of the other report. We tried to anticipate the most common applications of this capability, e.g. look at a report on the screen before directing it to a print file. "REPORT IPCSPRNT" gets that job done. What you'd use, assuming it met your needs would be "REPORT %myroutine".
