ILE Conversion

[Mark Walter <mwalter@xxxxxxxxxx>]

All,

I have been assigned the task of converting a HUGE monolith of a program 
into more manageable pieces. I have been working with RPG IV now for about 
4 years and have been creating small ILE programs utilizing sub-procedures, 
service programs, and the rest of that good stuff for about a year. This is 
the first very large project I will be attempting and I have a few 
questions.

Regarding screen handling: The current program maintains 10 screens in one 
display file. Would it be advantageous to place each display format in it's 
own display file or to continue to place all of the screens in one display 
file and just maintain each format in it's own module.

Regarding externalizing I/O: I would appreciate any input and experiences 
on this. I'm sort of on the fence about this one. I read the chapter in the 
Redbook about it and it seems interesting however it also seems like a lot 
of work to implement.

Any stories, gotchas, or experiences regarding a large conversion project  
 would be appreciated.

Thanks in advance

Mark
