Hi,
I'm trying to use a 12F509 for the first time. I don't even know how to address the I/O pins. It appeared from the datasheet that they were addressed as 'GPIO', or possibly even PORTB.

I just want to set the TRIS register but PicBasic Pro barfs at both of these:

TRISGPIO=%111111

(or)

TRISB=%111111

Thanks for the point in the right direction!!
