I have created a command that display Source file and library. Now i want that when i enter library name and press f4 on Source file, pgm should display all the PF- SRC's in that Library. For F4 option i have used Choice program but since only limited paramters are passed in Choice pgm i am not able to paas library name and further can't call a pgm that will display list of Source files. Below is the Code snippet for CMD type object :- CMD PROMPT('Source Scan for HUB Standard') PARM KWD(SOURCE) TYPE(*CHAR) LEN(1) RSTD(*YES) + VALUES(N A) MIN(1) + CHOICE('N,A') PARM KWD(SRCFILE) TYPE(FILE) RSTD(*NO) + PROMPT('SOURCE FILE') FILE: QUAL TYPE(*NAME) LEN(10) RSTD(*NO) EXPR (*YES) + CHOICE(*PGM) + CHOICEPGM (XXXXXLIB/YYYPGM) QUAL TYPE(*NAME) LEN(10) DFT(*LIBL) + SPCVAL((*LIBL)) EXPR(*YES) PROMPT ('Library') Below is the Choice pgm:- PGM PARM(&PARM1 &PARM2) DCL VAR(&PARM1) TYPE(*CHAR) LEN (21) DCL VAR(&PARM2) TYPE(*CHAR) LEN (2000) IF COND(%SST(&PARM1 1 10) = 'CHOICE ' *AND + %SST(&PARM1 11 10) = 'SRCFILE ' *AND + (%SST(&PARM1 21 1) = 'C' *OR %SST (&PARM1 + 21 1) = 'P')) THEN (DO) /* (%SST(&PARM1 21 1) = 'C' *OR %SST (&PARM1 + */ CHGVAR VAR(&PARM2) VALUE('Name, F4 for List') ENDDO IF COND(%SST(&PARM1 1 10) = 'CHOICE ' *AND + %SST(&PARM1 11 10) = 'SRCFILE ' *AND + %SST(&PARM1 21 1) = 'P') THEN (DO) CHGVAR VAR(&PARM2) VALUE('Name, F4 for List') CALL PGM(GTSQL) PARM ('XXXXLIB') return ENDDO Thanks in Advance for looking into.
