cosmetic changes
Because of the refactoring of this routine, Unit Tests on A1AEPSVR started failing. I fixed the error here dealing by empty-stringing the unpassed parameters from A1AEPSVR
Added assertion text for the two assertions to help me in debugging. I now fixed the issue.
Added variable A1AEUT1IEN which is a leaking variable that suppresses interactive dialog so that the routine can be Unit Tested. Used by A1AEUT1.
Added 2 Unit Tests and removed 1 unused one.

Removed PATCH999 (not used any more).
Added PATCHEX to test ^A1AEM2K.
Added WRITEID to test ID11005 and STREAMID^A1AEUTL.
