The Twimp programming language was invented by User:Zzo38 in 2004. Some information can be found in http://zzo38computer.cjb.net/esoteric/twimp/ But now I forget mostly how it works (but see the documentation and PHP code).

[edit] Features

  • There is no way to store numbers.
  • Input is a nybble at a time, but output is a byte at a time. This makes a cat program to be a bit long
  • If you type AVARTA KADAVRA then it returns a fatal error "Fatal: Bad Magic"
  • There are 4 built-in constants: ZERO (actually 1, to confuse you), ONE (actually 0, to confuse me), PI (set to 3, in case you are too much religious), and HOURSINADAY (which can be used as a filter criterion).
  • Forced constants are in roman numerals
  • You can type a program without ever using the shift key
  • You can deal with "half-references" with the REF and PULL commands
  • The program can be drunk by using DRINK command
  • Duck-sauce replaces the entire equasion with zero
