Display Cmd String Behind Menu Option: UPDATED Published by: Bob Cozzi on 02 Oct 2014 view comments

Display Menu Option (DSPMNUOPT) Command

The DSPMNUOPT command writes the CL command behind a menu option to the joblog as a message. Used from Command Entry, the user can view the program or CL command stored behind any classic user-created Menu option. This command supports only the IBM style Menus that use DDS and a message file to store the menu. It does not work with UIM menus or 3rd-party menus.

[UPDATE: I've updated the command since it was originally posted. This version now accepts OPTION(*ALL) for the menu option. When OPTION(*ALL) is specified, all menu options are listed with their corresponding command/program-to-call. In addition the OPTION parameter now defaults to *ALL.]

DSPMNUOPT:  CMD        PROMPT('Display Menu Option')          
            PARM       KWD(MENU) TYPE(QMENU) MIN(1) PROMPT('Menu')    
QMENU:      QUAL       TYPE(*NAME) LEN(10) EXPR(*YES)                 
            QUAL       TYPE(*NAME) LEN(10) SPCVAL((*CURLIB) +         
                         (*LIBL)) DFT(*LIBL) EXPR(*YES) PROMPT('Library')        
            PARM       KWD(OPTION) TYPE(*INT4) DFT(*ALL) RANGE(1 99) + 
                          SPCVAL((*ALL 0)) PROMPT('Menu option')       

The CL routine that drives the DSPMNUOPT command follows:

DSPMNUOPT:  PGM        PARM(&MENU &OPT)                   
            DCL        VAR(&MENU) TYPE(*CHAR) LEN(20)
