Displays variables and expressions that have been specially selected for attention. Whenever KCML executes a statement in the debugger it will update the contents of the watch window to reflect the new values of the expressions.

Pretty much any text string can be added to represent an expression. If the expression isn't valid for whatever reason then the result is displayed as '???'.

Adding a variable or expression

There are several ways to add an expression or a variable to the watch window.

• New - From this windows context menu. Allows you to freely enter text.
• Watch Variable - From the Editor window's context menu.
• Watch Variable - From Either the Local or Current Variable windows context menus.

Context Menu

The context menu gives us the opportunity to add/delete/edit an expression at anytime. It also allows us to use these expressions as the basis for traps.
