Delete Overlay (DLTOVL)

The Delete Overlay (DLTOVL) command deletes an overlay from the specified library. If the overlay is found, it is deleted. If the overlay is not found, a message is sent to the user stating that the overlay could not be found.

Parameters

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

Overlay (OVL)

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

This is a required parameter.

Qualifier 1: Overlay

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

Qualifier 2: Library

*LIBL
All libraries in the library list for the current thread are searched until the first match is found.
*CURLIB
The current library for the job is searched for overlays to delete. 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.
*ALL
All libraries in the system, including QSYS, 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   QUSRDIRDB   QUSRVI
QGPL        QSRVAGT     QUSRIJS     QUSRVxRxMx
QGPL38      QSYS2       QUSRINFSKR
QMGTC       QSYS2xxxxx  QUSRNOTES
QMGTC2      QS36F       QUSROND
QMPGDATA    QUSER38     QUSRPOSGS
QMQMDATA    QUSRADSM    QUSRPOSSA
QMQMPROC    QUSRBRM     QUSRPYMSVR
QPFRDATA    QUSRDIRCF   QUSRRDARS
QRCL        QUSRDIRCL   QUSRSYS

  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.
name
Specify a library name. Only the library named in this parameter is searched for overlays to delete.

Examples

Example 1: Deleting Overlays in All Libraries 

DLTOVL   OVL(*ALL/OVL1)

This command deletes all the overlays named OVL1 in all the libraries, including all IBM-supplied libraries.

Example 2: Deleting Overlays in Current Library 

DLTOVL   OVL(*CURLIB/OV*)

This command deletes all the overlays that begin with the letters 'OV' in the current library.
