RE: Subprocedure Question

It's just my opinion, but I don't see much benefit in externalizing file
I/O in RPG.  You have to hard code the file name and/or record format
name.  It's true you may not have to recompile as many programs when you
change a file, but there is the effort involved in creating the I/O
routines. The key is how often files are changed vs the effort necessary
to create the I/O modules.

<><><>Thank you everyone.  This information is very helpful.  I
<><><>am thinking of using service program to gain the ability
<><><>to make changes without having to recompile.  But Paul's
<><><>warning about potential file sharing conflicts concerns
<><><>me.  Is there a way to avoid these conflicts and still
<><><>use service program?  I know we are going to run into a
<><><>problem where I have two programs reading the same file
<><><>and in the same application.

<><><>Thanks.
