Chinese character generator - 300K

Recoding U< and <

Bill Mensch's implementation:

: U<    ( n n - f )
        2 dup xor 0<
        if  nip 0< exit
        then - 0<   ;

: <     ( n n - f )
        2dup xor 0<
        if  drop 0< exit
        then - 0<   ;

Better implementations:

code u< - ifnc 0 else -1 then

: <     ( n n - f )
        80000000 + swap 80000000 + swap u< ;

Forth features:

• lack of persistent data
• large building blocks
• sub-linear complexity (the size of the program grows with increasing functionaility at a rate less than either other high-level languages or assembly language)
• implicit parameter passing (on stack)
• ability to test interactively during development
• build on working routines
• extensible
