F9 - BUILD A SALVO TABLE
The F9 function key initiates building or editing a take salvo. The
cursor position prompts source and destination address fields.
Keyboard arrows move around the list.
A single source may be connected to multiple destinations in the salvo,
but when multiple sources are connected to a single destination, the last
entry over-rides any predecessor.
ESC ends the table-editing session. The program asks whether or not
to save the table to disk. If the answer is yes, The program requests
a filename. The program assigns the file extension .SVO to the entered
file name. The file name must be eight characters or less, so no path
prefixes are permissable. If the answer is no, the salvo remains in
memory, and can be sent (F2) or re-edited.
