And this is the reason we need GOTO.  Keep your loops to one printed page
(or one CODE/400-CodeStudio page, depending upon font and monitor size), use
GOTO to control major changes in program operation, move reusable code to
subroutines, and don't let DO loops DO you in.

You know that.  I know that.  Unfortunately, the people who originally wrote
the code didn't really worry about such things.  When working on RPG III
code for a customer who insists on keeping it RPG III, it's difficult to
create a meaningful subroutine name with only six characters to work with.
If I'm feeling ornery, I resort to SR0001, SR0002, SR0003...

The kind of code I'm talking about is when somebody discovered *IN03 DOWEQ
'0', and a thousand lines later the matching END.  Then, wrapped in that,
there's an EXFMT, *IN03 IFEQ '0' and 998 lines later comes the END.  And
then...

Yuck.
