A TopMenu presents a pull-down menu on the form associated with actions defined by the current interactive instruction in the BDL code.
When a TopMenu command is selected by the user, the BDL program triggers the action to which the TopMenu command is bound.
A TopMenu can be defined directly in the form or in a resource file with the extension 4tm.
See the topic on TopMenus in the Genero BDL User Guide for more information.
