I want to run my motors connected to PIC16F628A ..? I need PIC BASIC code?

Question

I have a PIC16F628A, and I have 2 motors coonnected to pins of that PIC. Pins RB0 and RB1 are connected to right motor. Pins RB2 and RB3 are connected to left motor. I'm using MPLAB as compiler from .pbp to .hex. I want to write a PIC BASIC program (.pbp) that will move one of these motors( for ex: left one) ... I have just written a simple code segment like this.

TRISB= %11110000

PORTB.2=0 
PORTB.3=0

MAINLOOP:

PORTB.2=1 
PAUSE 50 
PORTB.3=1 
PAUSE 50

GOTO MAINLOOP

END

Compiler compiles it correctly, after I burn the hex file successfully, I place the pig, then I start it, I see nothing...! I'm really so amateur in this programming language, I just want to ask that do I need to write any other code segment to run my motors? Or is there anybody who had such kind of project before?

It's not possible to tell where your problem is with the information we have. Can you test the voltage on the pins on the port to see if it changes when the PIC is powered on? You might have to disable the comparators (by writing the correct value to `CMCON` - see the [datasheet](http://ww1.microchip.com/downloads/en/devicedoc/40044f.pdf)). — Mathew Hall, Jan 09 '13 at 15:52
