I hear you.
Not to brag, but in my copious spare time at one organization I wrote a program to convert BASIC/400 code to RPGLE. (Ok, so I'm bragging). Were I in your Jimmy Shoes, I might consider something along those lines before I tried to rewrite the code. But I digress.

Did I see the word "the" in your opening sentence? Does that mean that when you write new code, you don't get told to rewrite it in "S/3-era matching..." style because "free form" and "ILE" are too difficult for other staff to understand and maintain?
Oops. Ranting and whining. Sorry.
Maybe I need a new career. Does anybody need a teacher. "Those who can't do, teach".
Full of quotes today,

P.S. I know you are correct. I have issues.

I am the active maintainer of a S/3-era matching record program which sees daily use. Yes, I am the Last of the Matching Recordians. This thing has program described I specs, program described O specs (for disk files as well as printer files. Thousands of lines of left-indicator goodness. It's hard to modify without a cascade of unintended consequences.
One of the very first things I did when I had to add code to this thing was to make the additions sub-procedures. Saved my life. Because instead of having a variable be changeable throughout all thousands of LOC, I can have isolated variables which can only be read and written inside that sub-procedure. Local scope is the best!
Every time I add a new sub-procedure to this, the program becomes more resilient, less buggy, and easier to understand. So it is absolutely possible to add sub-procedures to enhance code - even ancient code - incrementally and safely. No need to do a mass conversion or anything drastic.
