Scheme 48 is a programming language, a dialect of the language Scheme, an implementation using an interpreter which emits bytecode.[2] It has a foreign function interface for calling functions from the language C[3] and comes with a library for regular expressions (regex),[4] and an interface for Portable Operating System Interface (POSIX).[5] It is supported by the portable Scheme library SLIB, and is the basis for the Scheme shell Scsh.[2] It has been used in academic research.[6] It is free and open-source software released under a BSD license.

It is called "Scheme 48" because the first version was written in 48 hours in August 1986.[7] The authors now[when?] say it is intended to be understood in 48 hours.[citation needed]
