The alphanumerics memory is divided up into 22 lines of 80 characters.
(see Appendix ).
The alphanumeric characters that are available are alphabetical
upper case and numbers plus several special characters. Options
exist to choose the colour and priority of the alphanumeric
display.
Commands associated with alphanumeric display are:
LABEL/DISPLAY - load a string into the alphanumeric memory
CLEAR/ALPHA - clear the alphanumeric display
There is also an option in the LABEL/DISPLAY command to use the overlay
channel for text (with higher resolution) instead of the alphanumeric memory.
