The Work with Message Queues (WRKMSGQ) command shows a list of message queues and allows you to display, change, delete, and clear specified message queues.

Restrictions:

• Only the libraries to which you have use (*USE) authority will be searched.
• Only the message queues to which you have some authority will be shown on the display.
• To perform operations on the message queues, you must have *USE authority to the command used by the operation, and the appropriate authority to the message queues on which the operation is to be performed.

Parameters

Keyword	Description	Choices	Notes
MSGQ	Message queue	Qualified object name	Required, Positional 1
	Qualifier 1: Message queue	Generic name, name, *ALL
	Qualifier 2: Library	Name, *LIBL, *CURLIB, *USRLIBL, *ALLUSR, *ALL

Top

Message queue (MSGQ)

Specifies the message queues to be shwon on the Work with Message Queues display.

This is a required parameter.

*ALL

All message queues are shown.

generic-name

Specify the generic name of the message queues to be shown. A generic name is a character string that contains one or more characters followed by an asterisk (*). If a generic name is specified, all message queues that have names with the same prefix as the generic name are shown.

name

Specify the name of the message queue to be listed.

Qualifier 2: Library

*LIBL

All libraries in the library list for the current thread are searched. All objects in these libraries with the specified object name are shown.

*CURLIB

The current library for the thread is searched. If no library is specified as the current library for the thread, the QGPL library is searched.

*USRLIBL

If a current library entry exists in the library list for the current thread, the current library and the libraries in the user portion of the library list are searched. If there is no current library entry, only the libraries in the user portion of the library list are searched.

*ALLUSR

All user libraries are searched. All libraries with names that do not begin with the letter Q are searched except for the following:

#CGULIB     #DSULIB     #SEULIB
#COBLIB     #RPGLIB
#DFULIB     #SDALIB

Although the following Qxxx libraries are provided by IBM, they typically contain user data that changes frequently. Therefore, these libraries are considered user libraries and are also searched:

QDSNX       QRCLxxxxx   QUSRIJS     QUSRVxRxMx
QGPL        QSRVAGT     QUSRINFSKR
QGPL38      QSYS2       QUSRNOTES
QMGTC       QSYS2xxxxx  QUSROND
QMGTC2      QS36F       QUSRPOSGS
QMPGDATA    QUSER38     QUSRPOSSA
QMQMDATA    QUSRADSM    QUSRPYMSVR
QMQMPROC    QUSRBRM     QUSRRDARS
QPFRDATA    QUSRDIRCL   QUSRSYS
QRCL        QUSRDIRDB   QUSRVI

1. 'xxxxx' is the number of a primary auxiliary storage pool (ASP).
2. A different library name, in the format QUSRVxRxMx, can be created by the user for each previous release supported by IBM to contain any user commands to be compiled in a CL program for the previous release. For the QUSRVxRxMx user library, VxRxMx is the version, release, and modification level of a previous release that IBM continues to support.

*ALL

All libraries in the system, including QSYS, are searched.

name

Specify the name of the library to be searched.

Examples

WRKMSGQ   MSGQ(PERSLIB/MQ*)

This command displays the Work with Message Queues panel, showing a list of all message queues whose names begin with the letters 'MQ' that exist in library PERSLIB.
