All, >From the research I have done I agree with Walt in that it¹s a TSO restriction.
If you logon (Full screen mode) and enter a numeric Userid you get the not valid message, press F1 and there is the message from TSO. Hence, my thinking I may be able to get at the field in a TSO EXIT and bypass the numeric check. The fact that ACF2 supports it means it can be done and from what I am seeing there are no issues with MVS commands, INTRDR, etc. Looks like I go back to the manuals to see if I can figure this out.
