EXIT CONSTRUCT instruction
The EXIT CONSTRUCT instruction terminates the CONSTRUCT
instruction and resumes the program execution at the instruction
following the INPUT block.
Performing an EXIT CONSTRUCT instruction during a dialog is equivalent to
canceling the dialog: No field validation will occur, and the AFTER FIELD or
AFTER CONSTRUCT blocks will not be executed. The dialog is exited immediately.
However, INT_FLAG will not be set to TRUE as when the cancel
action is fired.
