Format of REQ, FIELD A, FIELD B, and RESOURCE fields

Field Contents
REQ
Byte 0 and
byte 1,
bits 0-3
For system entries, byte 0 and byte 1 (bits 0-3) usually contain the request code relating to the type of CICS® management involved. For user entries, these bits are not used.

Byte 1,
bits 4-7
These bits indicate the type of entry, as follows:
X'2' User entry
X'3' LIFO system entry
X'4' System entry
X'5' LIFO response/return
X'D' Trace on/off entry
   
FIELD A
