Examining Values and Data

An evaluation is a one-time spot-check of the value of an expression. You can evaluate expressions at any time from the editor window or the Debugging window. You can track the changes in a value each time the program stops using the Data Display window.

The results of an evaluation are listed in the Data History pane of the Debugging window. A dashed line indicates that the evaluation context has changed since the last evaluation. The Data History pane maintains a list of expressions you previously evaluated in a history list. You can clear the Data History pane at any time by choosing Data > Clear History.

To evaluate an expression using the editor window, select the target variable or expression in the source display. Then do one of the following:

• Click the Evaluate button or choose WorkShop > Evaluate > Selected to find the value of the selected expression.

• Click the Evaluate * button or choose WorkShop > Evaluate > As Pointer to evaluate where a pointer-type expression points.

The value is shown in the Data History pane. A separator line is inserted into the Data History pane list whenever the evaluation context changes.

To evaluate an expression using the Debugging window:

1. In the Expression text box, type or paste the variable or expression.

   If the expression you want to examine is visible in the Debugging or editor window, you can select the expression, then choose Data > Evaluate Selected.

2. Click the Evaluate radio button.

3. Click the Evaluate button or choose Data > Evaluate Selected.

   While the program is stopped, you can change the value of a variable or expression using the Assign button.
