We have a requirement to attach user modules from an unauthorised library and execute them from an STC which
runs APF authorised. Calling ATTACH with RSAPF=YES seems to do exactly what I want but every time I try it I get abend S306-0C, "authorised program attaching module from an unauthorized library". The ATTACH macro description states: RSAPF=YES when these conditions are met: . The caller is running in supervisor state, system key (0-7), or both . The caller is running non-APF authorized . The subtask is attached in the problem program state and with a nonsystem key. Conditions 1 and 2 seem mutually exclusive. I tried coding MODESET MODE=SUP and adding SM=PROB,KEY=PROP to the ATTACH but it made no difference. I seem to be missing something fairly massive here! Can anyone shed some light on this?
