Welcome to the list - if I understand right, your code works fine when=20
the PIC is programmed, just not in gpsim.
I googled it and as I assumed discovered that it is simulation software=20
for PICs - the main page notes under support:

Thegpsim-devel=20
<http://lists.sourceforge.net/lists/listinfo/gpsim-devel>mailing list is=20
devoted to gpsim specific issues. While primarily intended for gpsim=20
development, this list may also be used as a user resource to ask any=20
question.

Judging from this I think your question would be welcomed at the mailing=20
list (and more likely get a quicker/better answer)
Hope this helps a bit - good luck..
