Structured field introducers for messages and message variables

The structured field introducers described in Table 1 introduce messages and message variables that the DFSMSrmm API places in your output buffer:

MSGL is used when OUTPUT=LINES.
MSGN and ENTN are used when OUTPUT=FIELDS.
The SFI definitions are enclosed in single quotes (') to signify that they are 8-byte values and the two spaces are inserted for readability.

The MSGN and ENTN structured field introducers are always grouped within the MESSAGE group. The MSGL structured field introducers are grouped within the MESSAGE group when the DFSMSrmm API is unable to determine which subcommand type the message is for. One or more structured field introducers other than ENTN might follow MSGN as described in Messages and message variables structured field introducers.
