Hi John
Maybe I am not understanding what you are asking about
If you call a program, the program either needs parameters to run - hence a parameter list - or it doesn't
We have many programs that do not use parameters
Conversely - we have a large number of programs that do

Subject: [EXTERNAL] Parameter lists
Hi all,
In almost every RPG program i see parameter lists are extensively used. I like to know the advantage of see as i don't see it. It's rather unique to RPG, separating the list of parameters from the actual call.
Every time i see a call i have to go to the beginning of the program to see the actual parameters that are used. This, for me, is very inconvenient. I ever use them. The only "advantage" i see has something to do with "reuse".
Reuse is good, i wish it would be really used in RPG programs more (i.e.
service program and procedures etc). Instead, we got "parameter lists".
What is the advantage of parameter lists??
I suspect there is no advantage, just "we always do it like that". They were just introduced to cope with the limited punch card format. Same with key lists actually. But these days we don't have to use them anymore.
Provided free format RPG is used.
Parameter lists... does anybody know there advantage, besides obscuring the program??
