The query-by-example application demonstrates methods used to allow users to cancel
an interactive dialog statement using predefined actions and conditional logic.
You can handle user Cancel actions or interrupts gracefully during interactive dialog
instructions such as CONSTRUCT, using the built-in global integer
variable INT_FLAG and the DEFER INTERRUPT statement.
Use conditional logic statements to test for user cancel or interrupt actions and
specify statement blocks to execute conditionally based on the results.
