That sounds like it could get into sticky difficulties with
dependencies...
Try something like this:
ifdef __16F84
include "p16f84.h"
else
include "p16f84a.h"
endif
And then you can add "-p16f84" or "-p16f84a" to your gpasm command line
as appropriate.
Having said that, I think the '84 and '84a are identical as far as
simulation is concerned, so you needn't bother here.
I presume you've read the various reasons not to use the 16F84 anymore?
(More expensive and less capable than new chips like the 16F628, 16F88,
etc.)
