Amen to that.

Can't stand it but our ERP is built around that model.

Vern, you also could pass parameters over the LDA in RPGIII or RPGIV 😉

OK, bad wording on my part - "...before RPG IV..." would have been better, or maybe "...the only way in fixed format since whenever parameters could be specified..."

So, hardly " ... the only way ..."  :-o

I suspect that the conversion tool in RDi does not convert PLISTs, to

convert you have to use a tool like Linoma's or Craig Rutledge's or do

it by hand.

Yes, i wasn't clear.

I mean what is the advantage of using PLIST's.

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

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??
