by default, labels are case sensitive.  A quick look at P16F84.inc shows
that it defines "INTCON", and not "intcon"

there's a command-line switch, and probably an assembler directive,
to turn off the case sensitivity.

I notice that the mpasm manual is quite fond of mixed-case labels ala
" variable RecLength=64 "
I always thought that was a really bad idea when things are case
sensitive.  Too many possible typo/thinko wrong spellings...
