Does an RB issue SVC-3, or is it the task the RB dispatches that issues
SVC-3? Does the RB remain

Aren't you conflating DETACH and DELETE?
A programmer who is ATTACHing with ECB the same load module multiple times
should issue one DETACH for every ATTACH, no?
seriatim.
They led me to consult the assembler services reference, and t
