Also start rebol as cgi, ie: rebol -c vt.r otherwise these escapes will not work. } Email: %jeff--rebol--com library: [ level: 'intermediate platform: none type: 'tool domain: 'text-processing tested-under: none support: none license: none see-also: none ] Version: 1.0.0 ] foreach [name letter] [up "A" down "B" right "C" left "D"] [ set name func [arg] reduce bind [ 'rejoin reduce ["^(escape)[" 'arg letter] ] 'letter ] clr: "^(escape)[H^(escape)[J" jump: func [x y][ rejoin ["^(escape)[" x ";" y "H"] ] do example: [ print [ clr jump 10 10 'R up 4 'E left 13 'B down 10 'O right 30 'L ] ]
