Read More! More information concerning use of the keyboard is found in
sections Using the Keyboard Display (p. 382) and Read More! To implement
custom menus, see CRBasic Editor Help for the DisplayMenu() instruction.
CRBasic programming in the CR800 facilitates creation of custom menus for the
external keyboard / display.
Figure Custom Menu Example
(p. 70) shows windows from a simple custom menu
named DataView. DataView appears as the main menu on the keyboard display.
DataView has menu item Counter, and submenus PanelTemps, TCTemps and
System Menu. Counter allows selection of one of four values. Each submenu
displays two values from CR800 memory. PanelTemps shows the CR800 wiring-
panel temperature at each scan, and the one-minute sample of panel temperature.
TCTemps displays two thermocouple temperatures.

Custom menus are constructed with the following syntax before the BeginProg
instruction.
