Ok, you've got me interested now :)...

Whaddya mean "a little recursion"?  And no spacing?...do you mean in the memory there's no spacing or something?  Sorry, I'm
being thick =)

Now, when people are talking about BASIC compilers, we are all thinking along the same lines?  I'm thinking about a program
on-calc that takes the BASIC program you specify and turns it into an ASM program.  Right?
