Sh*t... should have a better look at TFM! 574 pages and I still can't
understand the basis of the language!! 8(
I'm finding Rebol more challeging than any ASM I've tried... here usual
programming logic seems to be messed up...
I'll try later with my head shakered... next I'll knock it against the
edge of the desktop... and if still does not work I'll start using heavy
drugs... maybe that way everything will be clearer...
