Yes TRIS will work... but you need to use the according name as per the datasheet.... TRISIO will do the job as expected.

Sure the PBP handbook will not cover it. TRISIO, TRIS is not a PBP command, just a PIC register.

You could still use

INPUT GPIO.0
OUTPUT GPIO.1
and so on.

TRISIO= %00000001 ' set GPIO.0 as input, other to output... when possible (MCLR)

it's not a bad idea to set initial value to your PORT as well.

Don't forget, all i/o are set as input at POR.

try this one
