Just looking at "ROI" does NOT tell the full story. Accountants have
words for some of the things you cannot quantify that are ex/treme/ly
important to a company's ongoing bottom line. "Goodwill", for example.
"Retention" is another. There's a "semi-retired" programmer where I
work, she works three days a week, but they prefer her over even an
experienced newcomer for her in-depth knowledge of the business.
Replacing a go-getter problem-solver with somebody for cheaper might
give you an "ROI" but it will cost profit in the long run.
Also, when they were new, I taught the AS400 to one shop that had just
acquired theirs to replace the S/36. The timing was /forced/ because
they were losing their best programmers to AS400 shops.
Good programmers that relish new methods and technologies as tools to
make their jobs easier are also the best problem-solvers for any kind of
situation.

Right-clicking to convert to free-form costs almost /*nothing at all*/,
and you get the whole thing in free-form then and there! That's an
"investment" of almost /*zero!*/
In your return on that cheap investment, your code is ready and set for
the easier maintenance that comes with free-form coding. Presto changeo!
The MOVE's are a ridiculously cheap price to pay for the benefit...
