/****************************************************************
  NAME         : OrderedHandlersToCode
  DESCRIPTION  : Prints out handler map -
                 the entire handler map
                 for a particular class is
                 guaranteed to be in the same
                 array partition
  INPUTS       : 1)  A buffer for the handler map file
                 2)  The base image name
                 3)  The id for this type of data
                 4)  The base image id
                 5)  The general header file
                 6)  A buffer for the version number of
                     the file for this type of data
                 7)  The maximum # of elements in any array
                 8)  A pointer to the class
                 9)  A buffer holding the handler map partition #
                 10) A buffer holding the handler map relative
                     index in the partition
                 11) A buffer for a flag indicating if the
                     buffer file can be reopened later
                 12) A pointer to the file info for
                     this data if the last file needs
                     to be reopened for termination
  RETURNS      : TRUE if all OK, FALSE
                 otherwise
  SIDE EFFECTS : Handler maps written
  NOTES        : None
