Overlay (OVL)

Specifies the overlay to work with. A specific overlay or a generic overlay can be specified.

This is a required parameter.

Qualifier 1: Overlay

*ALL
All overlays are worked with.
generic-name
Specify the generic name of the overlays to work with. A generic name can be specified as a character string that contains one or more characters followed by an asterisk (*). If a generic name is specified, all overlays that have names with the same prefix as the generic overlay name are worked with.
name
Specify the name of the overlay to work with.

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 job is searched for overlays to work with. If no library is specified as the current library for the job, QGPL is used.
*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 a library name. Only the library named in this parameter is searched for overlays to work with.

Examples

WRKOVL   OVL(*LIBL/OV*)

This command searches the library list to find the overlay objects whose names begin with the letters 'OV'. All overlay objects with names beginning with 'OV' are shown on the Work with Overlays panel. If no overlay objects beginning with 'OV' exist in the library list, the WRKOVL display is shown with a message indicating that an object matching the specified name cannot be found.
