In order to run BIM$CGRX in a dynamic partition, you must add the following to your SVA list, assuming you have the BIM-GSS 5.3A sub-library in your PHASE LIBDEF CHAIN: BIM$CGSV,SVA or add the following immediately after the BIM$INIT execution during IPL: SET SDL BIM$CGSV,SVA /* The above is only necessary if you run BIM$CGRX in a dynamic partition. If it is in a static partition, BIM$CGSV will be loaded into the SVA automatically. If you have any questions, contact CSI BIM-GSS support.
