muf

Multi User Forth

Advanced coding language used on MUCKs. When used by Zirik, it causes flooding.

MUF is frequently used when MPI proves insufficient to perform a desired function, as it has much greater capabilities. However, most consider it more difficult to learn.

Zirik wrote a program for underwater realms in MUF and inexplicably drowned the entire population of the MUCK.
