The executing one line at a time idea turned out to be a pretty good idea. That is enough to make Mac OS 9.2 boot. It is also entertaining to watch each executed line be printed to the terminal. Here is the patch:
[ LONG LINES ]
If you look at forth/bootstrap/interpreter.fs, you see EVAL already handles multiple lines, but only with unix line endings:
: evaluate ( str len -- ?? ) 2dup + -rot over + over do i c@ 0a = if i over - (evaluate) i 1+ then loop swap over - (evaluate) ;
So, change that instead? Or rewrite it, it's yucky. Bonus points if you also handle 0d 0a and 0a 0d line endings.
