If I did XMI0 then the string would hit.  The remaining 01 would be
ignored by the program.  That would be an unanticipated consequence.
So an error code is basically a few letters followed by numbers.  The
letters represent a group and the numbers represent a specific error
condition.  I'm trying to group them to reduce load on the program.  I
have to search for 1000 possible errors.
