(This might should have been OT -- it is sometimes hard to know exactly
where the dividing line might be).

Suddenly having a need for a C compiler, and having downloaded the PICCLITE
compiler (for which I am eternally grateful to Hi-Tech, for having made it
available at no charge to students and hobbyists, seeing as I consider
myself to be in both camps) I find a strange thing, and hope someone can
clear it up for me.

There are some sample programs, and one called METRO.C  (a metronome
program - surprise!!) seems to be one I can adapt for my metronome
project.  According to the comments, it is written for a 16C54
chip.  OK.  I can deal with that, thought I.  I want to use a 16F628 chip,
so obviously have to see what differences there are.  Not many, or at least
none that will prevent it from being used.

HOWEVER -- the program would not compile because there is an undeclared
variable, by the name of RTCC.  It appears to me that RTCC and TMR0 are the
same, and so this is not a big thing.  Except that I am curious as to why
they called it RTCC.  Is this a historical thing?  Did TMR0 used to be
called RTCC?  The data sheet for the 16C54 makes no mention of RTCC.

(I just know that someone is going to write me and tell me that I only have
to change it to TMR0.  Hey, I know that already!! :-)   I just wonder why
it was called RTCC.)
