INTERCALL

Hello World in INTERCAL language

INTERCAL is an esoteric programming language designed to be extremely difficult to understand. It is a parody of the FORTRAN and COBOL programming languages.

It was created by Princeton students Don Woods and James Lyons in 1972. The current version, C-INTERCAL, is maintained by Eric S. Raymond. The original authors say that INTERCAL stands for "Compiled Language With No Pronounceable Acronym" ("Compiled language with no pronounceable acronym")

One of the most peculiar features of INTERCAL is that instead of having the GOTO statement (discouraged by Edsger Dijkstra) it has the COME FROM # statement, which indicates that when the # statement has been executed, it jumps to the next statement after COME FROM #.
