True, but that does not necessarily imply -- the fact that filePro
doesn't care which case you press the key in -- that the *system dummy*
will return it's reply in a specific case.

Happens it will; I just tested it: even if you press "X", what you get
back in @BK is "x".  I don't know whether I think that's a feature or a
bug; I do know it's not documented.  *Anywhere* -- it should be in
18.11.2.11 of Stuart's fourth, but it's not.

But more importantly, how come "=" is acceptable on an IF line?

I see that that is in Stuart's book, but ISTR that it used to give
syntax errors; when did it start working?
