The Expressions view allows manipulation of expressions. An expression is a snippet of code that is evaluated to produce a value. In Carbide they are defined using C/C++ expressions. Some expressions may need to be evaluated at a specific location in the program so that its variables can be referenced.
The Expressions view displays these panes:

Remove | Remove the selected expressions from the Expressions view list. |
Remove All | Remove all expressions from the Expressions view list. |
Find... | Opens a Find dialog to search the Expressions view list. |
Change Value... | Opens the Set Value dialog where you can modify the value assigned to the selected expressions. Change the value and click OK. |
Add Watch Expression... | Opens the Add Watch Exression dialog for creation of a new expression. |
Disable | Disables automatic evaluation of the selected expression and appends (disabled) to the expression name. Useful when you have lots of expressions but are concentrating on only a few. The more expressions that need evaluaton, the longer it takes to update the Expressions view. |
Enable | Enables automatic evaluation of the selected expression. Enables a disabled expression so that it is evaluated during the debug session. |
