I coded the PIC16F1937 and the PIC16F1000 into gpasm back in the day.
The F1000 is a pseudo part simply for testing.
It sounds like the patches were not applied to the general build so
these devices do not exist.

Thanks Joseph
So, the 16f1933 has the enhanced instruction set but the current
version of gpasm does not seem to recognize it (I only tried
the BRA instruction for a quick test). In the absence of an option
to to pull in the extra instructions (I tried the -y option) I suppose
I need the old version. I see a thread back in June 2008 that
mentions the PIC 16 architecture but it doesn't seem to give
instructions on how to use it.
If I use an old version of gpasm, presumably it wont recognize the
16f1933. So, what is the procedure for getting it to emit the
enhanced code?
I'm using Debian.
Thanks again
Roger
