The Lesser-known Programming Languages #21: FIFTH

FIFTH is a precision mathematical language in which the data types refer to quantity. The data types range from CC, OUNCE, SHOT, and JIGGER to FIFTH (hence the name of the language), LITER, MAGNUM and BLOTTO. Commands refer to ingredients such as CHABLIS, CHARDONNAY, CABERNET, GIN, VERMOUTH, VODKA, SCOTCH, and WHATEVERSAROUND.

The many versions of the FIFTH language reflect the sophistication and financial status of its users. Commands in the ELITE dialect include VSOP and LAFITE, while commands in the GUTTER dialect include HOOTCH and RIPPLE. The latter is a favorite of frustrated FORTH programmers who end up using this language.

The Lesser-known Programming Languages #18: C-

This language was named for the grade received by its creator when he submitted it as a class project in a graduate programming class. C- is best described as a "low-level" programming language. In fact, the language generally requires more C- statements than machine-code statements to execute a given task. In this respect, it is very similar to COBOL.
