Darn...I didn't read it as IF ... THEN since they are compile-only words! That is pedantic though. There was nothing wrong with alonz's answer. But just 'cause, here we go: :-p

: forth s" forth" ;
: you   s" cry" ;
: read  s" reads" ;
: kudos s" kudos" ;
: robbe s" robbe" ;

: cats
  2rot
  pad place
  s"  " pad +place
  pad +place
  s"  " pad +place
  pad +place
  pad count
  ;

: can? 
  2rot 2swap cats
  s" cry reads forth"
  COMPARE
  IF false
  ELSE true
  THEN
  ;

: get ( s1 s2 : "s1 gets s2" )
  s" gets"
  cats
  ;

: if?
  2 pick
  IF type ELSE ." Nope! No kudos!" THEN
  ;

CR
forth you read can? you kudos get if?
CR
forth robbe read can? robbe kudos get if?
CR

OMFG that is some bad code...it has been too long.

It's been a long time, but alonz's code looks more correct than yours (which *at least* misses a "then") ... assumed that "can?" and "get" are functions taking three and two arguments, respectively.

Nonono! You just reversed the infix! It should have been:

forth you read can you kudos get if

;-)

but forth is still easier to read than most perl, at least if you are used to HP calculators

Interesting. My reflex would have been to use a forth stack.

In the world of Micro Python drivers written in python are first class citizens and juggling registers/bitfields using named tuples offers a benefit of being more expressive. Having limited programming experience I find it more accessible than Arduino(s) world.
