Answer1:
More than one Database file can be joined by different ways
like..
1)Inner join or Join Logical file
2)Left outer Loin
3)Right outer Join
4)Self join
These all are join logical file.
Non Join Logical file means Simple Logical file i.e Only
one PF file.

PFILE is the necessary keyword for non
join logical file.

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.
