Will this work

cat VAR IN4

or do I need something like this

car VAR IN4.Bit1

I looked in help but it wasnt very clear.

Jon Williams

That will work, and cat will be defined as a bit-sized variable that will follow the state of P4 (make sure that P4 is an input, else it won't change).
In PBASIC 2.5 an easier way to do that is:

{$PBASIC 2.5}  
Cat    PIN    4
Dog    PIN    5
 
Setup:
  OUTPUT Dog
 
Main:
  Dog = Cat
  PAUSE 100
  GOTO Main
  
  

In this program Cat and Dog names assigned to P4 and P5, respectively.· On reset, all pins are inputs, so Dog (P5) is made an output.· The main loop causes the output from Dog to follow the input from Cat.· The equivalent code is:

Main:
  OUT5 = IN4
  PAUSE 100
  GOTO Main

Will this also work?

drive PIN 0

forward CON 500

MAIN:

PULSOUT drive, forward

PAUSE 20

GOTO MAIN

Yes it will. The compiler looks at the context in which you use a PIN defintion and will substitue the correct values or register bit.
