Have you read the help text for the Oshon basic compiler as it tells you how to do it ?

Config PORTB = Output
Config PORTC = Input
Config PORTC.3 = Input

When you have compiled, assembled and loaded your program you can then run it. Once it is running select "Microcontroller view" from the tools menu. You can now click on the "T" by the pins you want to turn on/off
