12c508a picbasic pro

Hi
I wrote a simple basic program for my PIC (12c508A) in a Picbasic Pro compiler
but I have this error after compilation "unable to fit variable soft_stack"
please see my program below and tell me the errors as I am beginner in PIC programming .
Thanks


lowinput VAR GPIO.0
overtemprature VAR GPIO.1
overload VAR GPIO.2
outputpin VAR GPIO.3
green VAR GPIO.4
red VAR GPIO.5
count1 var byte
i var byte

OUTPUT outputpin
input lowinput
input overtemprature
input overload
OUTPUT green
OUTPUT red

while i=0
if (lowinput=0) and (overload=0) and (overtemprature=0) then

outputpin =0
High green
Pause 500
Low green
Pause 500

ENDIF


if (lowinput=0) and (overload=1) and (overtemprature=0) then

while count1<2
gosub overloadmode
count1=count1+1
wend
outputpin =1

while count1<7
gosub overloadmode
count1=count1+1
wend

outputpin =0
count1=0
ENDIF

if (lowinput=1) and (overload=0) and (overtemprature=0) then

while count1<5
gosub lowinputmode
count1=count1+1
wend
outputpin =1
count1=0
ENDIF

Hi Omid,

First off OUTPUT is a reserved word and can't be used like you are using it. Second, GPIO.3 is an input only pin. You might want to goto www.picbasic.co.uk for additional assistance.
