That was my original route but got nixed (and I didn't disagree) due to how 
"BIG" that code would be
 
Master Fields = 52 in 1 file
Environment fields 220 across 7 files (some are common, such as SKU#)
 
Thanks for everyones input, working on cpl ideas from this list and will kepp 
y'all posted

Use RPG, break it into two pieces of logic: the first checks to see if
there is a match, the second updates the appropriate file.

/free

// See if data matches
match = (MFD = 'CORG' and CORG = MFV)
or (MFD = 'FLD2' and FLD2 = MFV)
(...)
or (MFD = 'FLDN' and FLDN = MFV);

// If a match, update a field
if match;
// File select 
select;

// Update INVMST
when EFL = 'INVMST';
getINVMST();
// Field select
select;
// BUYR field
when EFD = 'BUYR';
BUYR = EFV;
// Additional fields
(...);
endsl;
putINVMST();

// Additional files
(...);

endsl;
endif;

/end-free

Very readable, very fast. Yes, you have to maintain it to add fields,
but the tradeoff is simplicity and debuggability.
