Jacl: A Tcl Implementation in Java.

Jacl, Java Command Language, is a version of the Tcl [1] scripting language for the Java [2] environment. Jacl is designed to be a universal scripting language for Java: the Jacl interpreter is written completely in Java and can run on any Java Virtual Machine. Jacl can be used to create Web content or to control Java applications.This paper explains the need for Jacl as a scripting language for Java and discusses the implications of Jacl for both the Java and Tcl programming communities. It then describes how to use Jacl. It also explains the implementation of the Jacl interpreter and how to write Tcl extensions in Java.
