This is, after all, similar to the reason why there is so much COBOL code
around - because it works well and there's no real benefit to changing to
code in a different language (yes, I know that RPGIII and RPGIV are very
similar languages with code conversion utilities). COBOL is, after all,
significantly older than RPG.

Actually I think this is a false hypotheses.

"COBOL" has been around longer than "RPG". But just as there are flavors of RPG so there are with COBOL. The equivalent of RPG II in COBOL terms would be ANSI '68. RPG III would be ANSI '74 (I think) and RPG IV would be ANSI '85. Are there a lot of COBOL programs around? Yes. Are there many COBOL '68 around - none that I've seen in many years. Are there COBOL '75 programs around? A few - but most that I've seen have been updated with '85 features. When you consider the changes between ANSI '74 and '85 I would argue that there were fewer reason to change from '74 to '85 than there were for RPG III to RPG IV.
