ALGOL 68

Pretty much the only variant of the language that sees any use these days, and is in fact seeing something of a mini-renaissance. Algol-68 reached a surprising popularity in Holland with the universities there refusing to buy computer systems that did not support the language in the 70s. There is at the least one very good implementation for 32 bit OS/2 showed up in the form of OCCL Algol 68.

Other variations of the language include the Japanese ALGOL-N a simplified subset of Algol-68 that was quite popular in Asia in the 1970s in particular on Japanese computer hardware.
