The application "got abended" because something running under that task mis-issued DETACH.
The doc for completion code 23E reason 0 seems pretty clear. The entry requirement for DETACH is: R1 contains the address of a word which contains the address of the TCB of the task to be detached. If you provide the right positional parameter to the DETACH macro, t The most common error I have seen in DETACH is being off by a level of indirection in what was specified to DETACH, landing with R1 containing the address of the TCB.
