Old program was S/36, rewritten to ILE.  (Rental) order entry.
First screen offers user 10 different options, each initializing work and 
file values, specific to the option.  3rd screen has over 40 fields that 
continue to affect "down-stream" values.  Final screen is invoice totals 
and payment information.  I need to make sure the data coming out the back 
end coincides with options taken and values entered.  

Trust me - I wouldn't be bothering with it if I didn't need it.

And, Tom - you're right, seeing a subfile fill or array values initialized 
in a DO/FOR loop is a waste.  Fortunately for me, there aren't any 
subfiles, the DO loops are limited, and processing that takes place in 
them does need to be tracked.
