ADPLEXTN: (Mapped by mapping macro BLSABDPL) IPCS sets field ADPLEFCD to ADPLEFAC (X'0002') upon entry to an ASCB exit routine to permit a common entry point to serve as an ASCB exit routine as well as one of the following types of exit routines:
- ANALYZE exit routine
- Post-formatting exit routine
- TCB exit routine
- Verb exit routine
The registers and other conditions on entry to each of these types of exit routines are the same. Use field ADPLEXTN to determine the purpose of a given call to a multi-function entry point.
