[SOLVED] Is there a TSO command written in REXX or CLIST that can determine WHO has enqueued a dataset?

Is there a TSO command written in REXX or CLIST that can determine WHO has enqueued a dataset?

I need to write a REXX Exec or Clist to identify WHO has enqueued a Dataset and display a user friendly message on an ISPF dialog application. Due to system configuration issues, the %WHOHAS command is not available. However I also know that ISPF itself (Option 3.4) has proprietary hooks into the zos mainframe to display the enqueued resource information I need - so the infomation can be obtained. Unfortunately I don't know how to access this data from outside ISPF 3.4 using a REXX Exec or CLIST. Any suggestions?

Solution

This turned out to be a very simple fix. Nothing fancy. If the clist uses CONTROL NOFLUSH it will not abort when the ALLOCation of a dataset fails. We also have a installed product called TSOPLUS that will format a message to the terminal identifying who has allocated a dataset when the allocation fails. By turning off FLUSH and then systrapping the TSOPLUS message, I was able to extract the information I needed.
