Action views
Action views on a form such as Toolbars, Topmenus, and buttons, trigger actions defined in your program code.
The value of the name or the action property, must exactly match the name of an action in an ON ACTION clause of an interactive statement, such as MENU.
For example, a ButtonEdit on the form
with the action property value set to "search" would trigger the action "search" in
this BDL program code, when the MENU statement is active and the user clicks the
button.
