OK and Cancel buttons
Every custom dialog box must contain at least one command button: an OK button or a Cancel button. BlueZone Basic includes separate dialog box definition statements for each of these two types of buttons.
Example:
Sub Main
   Begin Dialog ButtonSample 16,32,180,96,"OK and Cancel"
   OKButton 132,8,40,14
   CancelButton 132,28,40,14
End Dialog
Dim Dlg1 As ButtonSample
Button = Dialog (Dlg1)
End Sub
