Create a template menu (m_template) 2.a) Create a function to dynamically add a menu item in the template menu:/* = = = = = = = = = = = = = = = = = = = = = = = = = = Function name: of _ add memo Description: Add a template menu item parameter to the specified menu: String as_tag (tag for creating menu item) Return value: succeeded1= = = = = = = = = = = = = = = = = = = = = = = = = = = = lm _ item m = create m _ template lm _ item . text = as _ text lm _ item . tag = as _ tag Li _ item count = upper bound(am _ menu . item[])Li _ item count = Li _ item count+ 1am _ menu。 item[Li _ item count]= lm _ item return 1b， Function for creating pop-up menu in template menu/* = = = = = = = = = = = = = = = = = = = = = = = = = Function name: of _ popmemeu Description: specified menu parameter: menu am _ menu(popup menu).
