Definition of message keyword related terms

The component-specific message keyword sections use the terms defined in Table 1.

Table 1. Definition of Message Keyword Related Terms
Term	Definition
Message identifier	A three-letter prefix to identify the component that produced the message and a message serial number to identify the individual message (for example, IDC3009I).
Message keyword prefix	The characters MSG, to which the message identifier is appended. This comprises the message type-of-failure keyword.
Return or reason code	A numeric code contained in the message text. Either the message text or z/OS MVS System Messages, Vol 1 (ABA-AOM), through z/OS MVS System Messages, Vol 10 (IXC-IZP), can identify the type of code.
Return or reason code keyword prefix	The characters RC, to which each return or reason code (exactly as it appears in the message) is appended. (Each code in the text requires its own keyword prefix.) This comprises a modifier keyword to specify the failure-related symptom.

Go to one of the procedures indicated in the following table.

Subcomponent	Procedure
DADSM/CVAF	See DADSM/CVAF—message keyword.
ISMF	See ISMF—message keyword.
OAM	See Object Access Method—message keyword.
SMS	See Storage Management Subsystem—message keyword.
VSAM Record Management	See VSAM, transactional VSAM and VSAM RLS record management—message keyword.
All other DFSMSdfp components	Continue below.

Append the message identifier to the keyword prefix MSG. Include in the keyword string any return codes and reason codes from the message text. Append the codes, exactly as they appear in the message to the keyword prefix RC.
Example: If the message identifier is IDC3009I, the return code is 04, and the reason code is 032, specify the keyword string as follows:
```
MSGIDC3009I RC04 RC032
```
Rule: For PDSE-related failures (IGW messages), use RSN as the prefix for reason codes and RC as the prefix for return codes.
Message text might contain additional information that you can use as modifier keywords (function, subfunction, device-related information, and so forth); record it on the Keyword worksheet.
For input/output or hardware-related errors, review the SYS1.LOGREC for keyword information.
