Group1's address formatting application Code1 ...
is "correctly"
referenced as CODE-1 Plus.
I'm not familiar with that company or software. But, if I ever had a
reason to write about it, I would do the same thing I'm doing now with
the Coleco computer -- I'd try to find out if the letters are a valid
acronym, and then I'd make a decision. If I found out that "CODE" does
not stand for anything, then I'd write Code instead. I'd tell anyone
who had a problem with that to explain to me exactly why "CODE" stands
for and why they ever capitalized it in the first place. If their
answer is, "Nothing, and because the company's brochures told us to,"
then I'd just laugh at them.
