The record that is returned from a command
request can contain none or many message text segments.
Each segment is a varying-length
message (LLZZ, where LL is the 2-byte length and ZZ is a 2-byte reserved
area) followed by message text. The IFCA's IFCABM field contains the
total number of bytes moved.
The following figure shows the return area after a START
TRACE command successfully executes. Figure 1. Example of IFI return area after a START TRACE command. This output was assembled with a user-written routine and printed
with DFSERA10 program of IMS

Description
A 007E0000
Field entered by print
program
B 0000007A
Length of return area
C 003C
Length of record (003C).
The next two bytes are reserved.

The IFCABM field in the IFCA would indicate that X'00000076' ( C + E )
bytes have been moved to the return area.
Each segment is a varying-length
message (LLZZ, where LL is the 2-byte length and ZZ is a 2-byte reserved
area) followed by message text. The IFCA's IFCABM field contains the
total number of bytes moved.
