Re: Return *on or *off from CLLE module

This is added for completeness for anyone reading this thread in the future.

SEU does not "understand" _anything_ added to any language since V6. That includes RTNPARM and many, many more features.

Just one more reason to dump the old dinosaur and use VS Code, or RDi, or miWorkspace, or Notepad++, or ... almost anything is better.

Thanks for the reply.

This worked but since it took me a while to figure it out using "old school"
formatting, I thought I would reply back with the code that I used to test
the concept.

--------------------
Program RTNPARMPGM
d rtnparmcl pr n rtnparm
if rtnparmcl();
dsply 'Success';
else;
dsply 'Failure';
endif;
*inlr = *on;
return;
--------------------
Program RTNPARMCL
PGM PARM(&STATUS)
DCL VAR(&STATUS) TYPE(*LGL)
CHGVAR VAR(&STATUS) VALUE('0')
ENDPGM: ENDPGM
--------------------
I compiled both sources to modules and then executed command CRTPGM
PGM(RTNPARMPGM) MODULE(RTNPARMPGM RTNPARMCL)

When I ran RTNPARMPGM, it properly displays Success or Failure (had to mod
the CHGVAR in the CL to test both results).

One other fun fact. SEU does not like the keyword RTNPARM but when you look
at the error message, it says RTNPARM is one of the value values. I know,
SEU is dead but it is still used in a lot of places so I thought that I
would point out this info because it took me a while to figure out what was
wrong with it.

I suggest you create the prototype for the CL where the first parameter is
the RTNPARM

The you can use it in RPG as a function ( as you describe) but the CL is
just the first parameter you have to set to LGL '1' or '0'

I define a lot of my RPGLE modules with a return type of indicator.
In the module, I return *on for success or *off for failure. If I
need more details from the module, I include fields as part of a parm
list. Then in my code, I can write something like this



If DoesCustomerExist(customerNumber);

// execute code based on customer existing

Else

// execute code based on customer not existing

Endif



Is there a way to return the *on or *off from a CLLE module? RETURN
does not have a parm.
