Wow that's an excellent idea!!

The IF/END-IF aren't so bad by themselves, but placed into already deeply nested condition statements, READ INVALID KEY statements, EVALUATEs, etc, that will make it a lot easier to maintain and read.

Also it will be far less likely that I will introduce my own bugs.

Thanks for the tip!

I will resolve by conditioning the DISPLAY statements (IF...END-IF) to not
execute during a prod run, that will be doable. But there are 100+ of them
for whatever reason???

What about conditioning all those DISPLAY statements with a D in column 7 so
that they get executed only when in COBOL debug mode (see STRCBLDBG)?

It should be easier to do, maybe even automatically with a small program
that reads the source and adds a D in column 7 whenever it encounters a
DISPLAY statement (provided it is the only statement in the line), and a D
in that column does not add all the clutter an IF...END-IF pair would do.
