Chapter 2. Tcl Interpreter and Language Basics

This chapter covers the following topics:

• Simple Variables in Tcl

• Procedures

• Arrays

• if Command

• switch Command

• Files

This is where the rubber meets the road. Without a fundamental understanding of the command syntax, you will be unsuccessful in writing any programs whatsoever. Reading and attempting to memorize command syntax can be arduous and boring. To really get an idea of how to use commands in this chapter, a better solution is to use them in practice.

Tcl interpreters are supported on Mac, UNIX/Linux, Windows, and other operating systems. You can visit the Tcl Developer Xchange website at http://www.Tcl.tk/ or perform a search for the latest Tcl interpreters.
