how can i stop the pic from sending a PWM???

wow.simple solution.haha.thanx a lot bruce.but are your coding mean i need to hold the push button to PWM on & release the button to PWM off...or push the button once to PWM on & push once again to PWM off????

Read the code! Do you see anything in that code saving the state of the button to remember for the next time the loop checks the buttons state?
The bit in the TRIS register follows the state of the push button...simple as that...just like it's written...

Yep. Like Ski said, that's how it works.

Here's another flavor.

Main:
  IF Push1=0 THEN
     GOSUB ChkState
  ENDIF
  GOTO Main    
  
ChkState:
  WHILE Push1=0       ' wait for button release
  WEND
  TRISC.2=TRISC.2 ^ 1 ' toggle TRISC.2 on button release
  RETURN

Endless simple possibilities.
