new to Pic Basic Need help plz

hello guys
what's wrong with this simple code?
as i guess it must keep at label "circoff" until portc.1 = 0 right ?
its not & jump to mainloop always

circoff:     
     if PORTC.1 = 0 then
     gosub   mainloop
     goto circoff     
     endif

thx for help

Hello Janosandi,
Of course you should set the fuse-bits and config everything at header before anything else. You would add these below lines to your code lines:

TRISC.1=1           ;Set the C.1 as an input pin

Definitely, a pull-up resistor should be ( you've set this pin as low active!) on C.1

And if you don't mind share your mainloop segment here.
