<

Tcl) An interpreted string processing
language for issuing commands to
interactive programs,
developed by
John Ousterhout at
UCB. Each {application
program} can extend
tcl with its own set of commands.
Tcl is like a text-oriented
Lisp, but lets you write
algebraic expressions for simplicity and to avoid scaring
people away. Though originally designed to be a "scripting
language" rather than for serious programming,
Tcl has been
used successfully for programs with hundreds of thousands of
lines.
It has a peculiar but simple
syntax. It may be used as an
embedded
interpreter in application programs. It has
exceptions and
packages (called libraries),
name-spaces
for
procedures and
variables, and provide/require. It
supports
dynamic loading of
object code. It is {eight-bit
clean}. It has only three variable types: strings, lists and
associative arrays but no
structures.
Tcl and its associated
GUI toolkit,
Tk run on all
flavors of
Unix,
Microsoft Windows,
Macintosh and
VMS.
Tcl runs on the
Amiga and many other
platforms.
Latest version: 8.0.3, as of 1998-09-25.
