PMFJI, but really, even for non-LE subroutines how hard is it to save your registers in your own R13 area, write an inline WTO with message indicating where and why you want to blow up and an ABEND macro right after? Yes, the WTO is non-reentrant. Making it reentrant is not that hard. IMHO an ABEND macro with a unique abend code is far preferable to any of the discussed techniques except during actual development unit testing (before any client/user ever sees it), but maybe that's just me.
