Variable Size 1 to 7 (including decimal point)
Decimal Point Position
(number of places after the
decimal point) 0 to 6 (the maximum value is one less than the
variable size selected above)
Suppress Zeroes
(appearing in front of the
first significant digit) Y(es) or N(o)
The variable symbol _ _ _
S_ _ will appear in your message at the variable’s
location.
The difference between a formatted variable entered with [CTRL][V] and an
unformatted variable entered with [CTRL][W] lies in the flexibility provided
by the ability to modify the parameters shown above.
Note that neither AutoRun Messages or Background Messages support
inserted variable data.
Change Formatted Variable With [CTRL][F]
Use [CTRL][F] to change the formatting parameters of a variable. To do so,
place the cursor under the symbol for the variable you want to change, then
press

Insert ASCII or BCD Variable With [CTRL][W]
You can send a single word ASCII or BCD variable for insertion into a
message. Use
[CTRL][W] to specify the insertion position. The software will
prompt you to specify either ASCII or BCD. The software will insert the
symbol for an ASCII or BCD variable (↕).
Note: BCD data consists of 4 digits per word, and ASCII data consists of 2
characters per word.
Note: Variables can be strung together to form compound variables up to 20
ASCII or 40 BCD characters long in any combination as long as the total
does not exceed 10 words.
