ZGOCALLOUTIN, ZGOTO level 0 with entry ref not valid when using call-ins
Call in/Run Time Error: Code invoked by a call-in contained a ZGOTO 0:entryref. The purpose of a ZGOTO 0:entryref is to "refresh" the GT.M routine context, but that action would invalidate the interface with the calling (in) code.
Action: Refactor the code invoked by the call-in to avoid or appropriately conditionalize the ZGOTO 0:entryref.
