You can customize the pull-down menus on the menu bar by adding and removing menu items and submenus.
You can add commands to a pull-down menu for easy access from the menu bar, while not losing a large amount of space on the screen. Commands can be displayed as a single item or grouped with similar items under a submenu. A pull-down menu can contain up to 999 commands. The command limit includes all menu items in a hierarchy. If the commands on the menu exceed these limits, the program ignores the extra commands.
If a pull-down menu is longer than the height of the screen, it is truncated to fit and the ability to scroll the menu is added. When the pointer cursor is near the top or bottom of the menu, the menu scrolls up or down automatically.
Pull-down menus should have one alias in the range of POP1 through POP499. Menus with an alias of POP1 through POP16 are displayed on the menu bar by default when the customization (CUIx) file is loaded. All other menus must be added to a workspace to be displayed.
