Thanks for sharing. I had a good laugh looking through your source and seeing that "kys" killed the interpreter. I threw together a trivial fizzbuzz in it for fun.
n = 1
goto main
#fizzbuzz
if n % 3 == 0 && n % 5 == 0
print "fizzbuzz"
goto increment
if n % 3 == 0
print "fizz"
goto increment
if n % 5 == 0
print "buzz"
goto increment
print n
#increment
n = n + 1
#main
if n <= 100
goto fizzbuzz
kys
