BCD Input - designates the location that contains the BCD value to convert. This can be any constant value or any readable numeric location.

 

Note: if the BCD Input location does not contain a valid BCD number, ST132 (Argument Out of Range) will be ON, and the System Error string $ERR will contain "Digit greater than 9 in BCDTO @xxxxxxxx".

 

Output - designates the location to store the Integer or Real result. This can be any writable numeric location.
