Watching variables and expressions
The Watch view lets you monitor the values of selected variables
and expressions as the application runs.
If the variable or expression is in scope, the Watch view
shows its value. Empty quotes indicate that the variable is in scope
but has not been initialized. A pair of glasses in the Watch view
indicates that the variable or expression is not in scope.
Setting variables and expressions in the Watch
view
You can select variables you want to watch as the application
runs by copying them from a Variables view. You can also set a watch
on any PowerScript expression. When you close the debugger, any
