(p. 510).
Menus for the integrated keyboard / display can be customized to simplify routine
operations. Viewing data, toggling control functions, or entering notes are
common applications. Individual menu screens support up to eight lines of text
with up to seven variables.
Use the following CRBasic instructions. Refer to CRBasic Editor Help for
complete information.
DisplayMenu()
Marks the beginning and end of a custom menu. Only one allowed per
program.
Note Label must be at least 6 characters long to mask default display clock.
EndMenu
Marks the end of a custom menu. Only one allowed per program.
DisplayValue()
Defines a label and displays a value (variable or data table value) not to
be edited, such as a measurement.
MenuItem()
Defines a label and displays a variable to be edited by typing or from a
pick list defined by MenuPick ().
MenuPick()
Creates a pick list from which to edit a MenuItem() variable. Follows
immediately after MenuItem(). If variable is declared As Boolean,
MenuPick() allows only True or False or declared equivalents.
Otherwise, many items are allowed in the pick list. Order of items in list
is determined by order of instruction; however, item displayed initially
in MenuItem() is determined by the value of the item.
