Alex, I'm not sure when random changed, but as it is currently defined, you can simplify random-tetromino a bit. Current definition:
: random-tetromino ( -- tetromino ) tetrominoes get dup length random swap nth ; Alternate: : random-tetromino ( -- tetromino ) tetrominoes get random ; Ed ------------------------------------------------------------------------- Using Tomcat but need to do more?
