Hi,
I'm just giving this nice compiler a try for the first time (usually I don't use
PICs...) and run into problems after the first few lines.
Using a 16C57, I want to set the Ports to their IO-functions.
Tried all possible ways to to it :

DIR GPIO b'00000011'
or
DIR GPIO IN
or
DIR PORTB.0 IN
or
dir PORTA b'00000011'
etc.
Everything compiles fine and without any error apart from the DIR commands:
Error: Invalid pin direction, expected In or Out
1153pic.txt (42): Error: Cannot set direction of individual pins on 12 bit core chips
1153pic.txt (42): Error: PORTI.O is not a valid I/O pin or port
1153pic.txt (42): Error: Syntax Error
1153pic.txt (51): Error: PORTA is not a valid I/O pin or port
1153pic.txt (58): Error: PORTC is not a valid I/O pin or port

So, what is the correct way to set the 16C57s Ports to their IO-functions ?
And, if GPIO is used, which of the ports is configured ? A, B or C ?
Version used is :
