1. Faster LEX. A reimplementation of the {Lex}

{scanner} generator by Vern Paxson .

{Flex::} produces {C::} and {aflex} produces {Ada}.

FTP flex-2.3.8.tar.Z from a {GNU archive site} or

{(ftp://ftp.ee.lbl.gov/pub/flex-2.4.3.tar.Z)}.

2. A {real-time} language for dynamic environments.

["FLEX: Towards Flexible Real-Time Programs", K. Lin et al,

Computer Langs 16(1):65-79, Jan 1991].

3. An early {object-oriented} language developed for the

{FLEX} machine by {Alan Kay} in about 1967. The FLEX language

was a simplification of {Simula} and a predecessor of
