Subject: AW: How to call a RPG program from a RPG program?

Nothing is wrong with RPGIV...
But why bother to build with the call command, passing this string to a
sub-procedure which itself calls QCMDEXC API to execute the call?
Why not calling it directly with the RPG command CALL or CALLP?
And if he wants to mimic the system procedure to call a program, why not
executing it directly?
And why an internal procedure, instead of having an external one (which
indeed exists!) to execute an CL command?

A new way to call a RPG program from a different RPG program!

I found the following code snippet this morning in a program written in
April 2012!!!

Both programs are written in RPGIV!!!

Aaaaaaaaaarrrrrrgh!



D DW_System PR 10i 0

d cmd 2048 varying value



D dsallpf ds qualified

D fil 10A

D lib 10A

...

/Free

dw_system('CALL PGM(DSYUNIQUE) PARM('''+

dsallpf.fil+''' '''+

dsallpf.lib+''' ''0'')');

...

/End-Free

P DW_System B

*

D DW_System PI 10i 0

d cmd 2048 varying value



d cmdval s 2046 based(cmdval_p)

*------------------------------------------------------------------------

c eval cmdval_p=%addr(cmd)+2

c eval cmdlen=%len(cmd)

c call 'QCMDEXC' 50

c parm cmdval

c parm cmdlen 15 5

c 50 return -1

c return 0

P DW_System e
