In Perl, scalar variable names all start with a dollar sign.  There are 
a mess of predefined variables with short names that are a dollar sign 
followed by a single, non-alphabetic character.  One of them is the 
variable $0 (dollar sign, zero) which contains the name of the program 
being executed.  That's where the name MV_DOLLAR_ZERO comes from.

As Peter said, whatever you put there will replace the word interchange 
in the logs so you'll want something that identifies which version (and 
instance) of interchange it is.  Change this to something different for 
each of your six instances and you'll be able to figure out which one is 
having problems.  As you say, it's probably one of the older two, which 
argues for an upgrade.
