Listing global variables

 

To list the current global Tcl variables:

1. Click the RCL Command: button in the Workbench window.

   A Commands dialog appears.

2. Pick the Global Vars choice in the dialog.

   A list of global Tcl variables matching the filter string in the dialog is presented.

3. Type in a new filter string and press the enter key to update the list.

   The filter string can contain wildcard characters: `?' will match any single character, and `*' will match a sequence of zero or more characters.

   

4. Select a variable from the list.
5. If desired, click Show Value to present the current value of the variable.

   Or double-click a variable from the list.

   If the variable is a scalar, then a message appears with its value. If the variable is an array, then a textual window appears, listing all the individual elements; you can have several such windows at the same time.

   

6. Click Done to dismiss these windows or the dialog.
