Re: RPG Cycle

I've not tested this... It uses the cycle for all I/O, and to end the 
program when all files have been processed completely.

OK.  Still the RPG cycle is 'supposed'  do handle all READS WRITES UPDATEs 

in hidden
manner.
The fact that the file IO in NOT specifically coded for is what confuses 
most
beginners.
Anyhow recently I had this case,
Order Header File (Keyed by Order number)
Order Detail File  (Keyed by Order Number,  Line Number)
Invoice Detail File (Keyed by Order Number , Line Number)
I asked a programmer to use Control breaks and MR to find
mismatched Headers and also mismatches between the Order Lines and Invoice 

Lines,
we had a problem using MR to find orphaned Invoice Detail Lines, we had to 

write
programs
the first using the Header as a primary file, the second used the Detail 
as 
the
Primary file.
Perhaps you have a suggestion how we can do this with one program.
