During a debugging session, you can use the following views to keep track of current values:
Variables view - Shows the values of all buffers, datasets, parameters, properties, variables, and temp-tables. Class variables, properties of a class type, arrays, buffers, temp-tables, datasets, and handle variables are all expandable in the view.
Expressions view - Shows the values of data elements that you explicitly choose to display, providing a convenient way to monitor a specific set of values that interest you. Class variables, properties of a class type, arrays, buffers, temp-tables, datasets, and handle variables are all expandable in the view.
The Expressions view duplicates and also expands upon information available in the Variables view. You can use the Expressions view to show ABL data (for example, ACTIVE-WINDOW or SESSION) that is not available in the Variables view. (You can also see this level of detail in the Variable Details view.)
Dynamic Objects view - Shows information about dynamically created database objects, user interface widgets, XML objects, and other objects that are active at the current state of program execution.
