The only examples are in the source.

  [ dup * ] is square
  [ dup 2 < [ drop 1 ] [ dup 1 - fact * ] ifelse ] is fact
  4 square .
  5 fact .

If you are familiar with Forth, Postscript, or Joy you should have no problems with programming in Fortik :)

Still, the idea of Fortik is to encourage students to learn how simple interpreters work and to extend the language.

Is the first assignment to reverse-engineer the language spec from the interpreter?
