Example Tcl Scripts

This section provides two example Tcl scripts. The first example is a “Sample Tcl Script for General Usage”. The second example is a “Sample Tcl Script for Advanced Scripting”.

You can run these example Tcl scripts the following ways:

•Enter each statement interactively at the xtclsh prompt (%).

You can access the xtclsh prompt (%) from the command line by typing xtclsh, or from the Tcl Console tab in Project Navigator.

•Save the statements in a script file with a .tcl extension. To run the Tcl script, type the following from the xtclsh prompt (%):

% source <script_name>.tcl
