- interchange file format — (file format) (IFF, full name "EA IFF 1985") A generic file format published by Electronic Arts as an open standard. IFF is chunk-based and hierarchical so files can include other files. It is easily extensible and an all round Good Idea. An IFF file starts with one of the following "group IDs": 'FORM', 'LIST' or 'CAT '. This is followed by an unsigned 32-bit number of bytes in the remainder of the file. Then comes an ID that indicates which type of IFF file this is. The main image type is ILBM, audio is either AIFF or 8SVX, animations are ANIM etc. An IFF file will probably have a filename extension related to this file type stored in the file. The rest of the file is divided into chunks each of which also has a four-byte header and byte count.

- parametric polymorphism — Polymorphism was first identified by Christopher Strachey in 1967 and developed by Hindley and Milner. For example we could specify that the argument of the "head" function was a list without specifying a type for the elements of the list. In Haskell we would write: head :: [a] -> a meaning head has type function from "list of a" to "a" where "a" is a type variable). This is known as parametric polymorphism. Polymorphic typing allows strong type checking as well as generic functions. ML in 1976 was the first language with polymorphic typing. See also generic type variable.
