This document contains code for a form application with labels, text boxes, buttons, and procedures to handle button clicks and text box navigation. When the "blagi" button is clicked, all text boxes are cleared and the first text box gains focus. When the "bexit" button is clicked, a confirmation message is shown and the form closes if confirmed. Pressing enter in each text box shifts focus to the next text box in sequence.
