Hi Tomas,

Thanks! Great!
It runs without problems.
I'm a little bit surprised, however, that it is so extremely slow.
When I tried this
(de fibo (N)
(if (> 2 N)
1
(+ (fibo (dec N)) (fibo (- N 2))) ) )
(fibo 36)
(bye)
I killed it after one hour :(
For comparison:
PicoLisp (64-bit) 6 sec
PicoLisp (32-bit) 11 sec
ErsatzLisp (Java version) 86 sec
So I tried some smaller arguments:
java wl ErsatzLisp Pil32 Pil64
+---------------------------------------
(fibo 22) | 25 0.19 0.015 0.016
(fibo 23) | 45 0.25 0.026 0.024
(fibo 24) | 69 0.36 0.041 0.039
(fibo 25) | 122 0.52 0.060 0.063
How can these huge differences be explained?

This produces a Celsius/Farenheit dialog. The input field does not
respond, however, and if I press the button it crashes with a
RuntimeException. Can the reason be that I'm usin OpenJDK?
Cheers,
