For Those of You Who Need to Debug Intercepts and Exits Inside Dynamic Allocation

We’ve just now pushed out an update (Z21-1505E) that adds support for a //xxxNOALC DD DUMMY jcl statement. When this ddname is present in the TIOT, z/XDC will abort any command or internal service that attempts to use Dynamic Allocation (SVC 99).

We want to thank Bob Edmond of BMC Software for requesting this feature.
