i never use Button statement. I prefer to use IF THEN or While Wend statement

TRISA=255
TRISB=0

IF PORTA.0 then ' if push button on PORTA.0 is pressed
     PORTB.0=1 ' set PORTB.0 to 1
     while PORTA.0 ' wait untill push button is release
     wend
     pause 50 ' debounce delay
endif

Be sure you refer to the great PIN... what your PIN statement refer to? Use the pin name make your code more readable or use alias

PushButton1 var PORTA.0

if PushButton1 then
   ' do something here
endif
