In addition to the input considerations described in Conditions on Entry to an IPCS Exit Routine, the following special input considerations apply to ANALYZE exit routines.

On entry to an ANALYZE exit routine, register 1 points directly to the IPCS exit parameter list (ABDPL data area).

Field ADPLEFCD of ABDPL is an exit function code. IPCS sets ADPLEFCD to ADPLEFAN (X'0001'). The ADPLEFCD field allows a user to write an exit routine that acts as both a verb exit routine, which formats data, and an ANALYZE exit routine, which simply reports on contention. The exit routine can follow a data area chain and perform formatting or call the CQE create service depending on the value in ADPLEFCD.
