    Summary: Print the name of a specific save slot

    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * HighlightSaveName calls PrintSaveName
             * MoveInLeftColumn calls PrintSaveName
             * MoveInRightColumn calls PrintSaveName
             * SVE calls PrintSaveName




 Arguments:

   A                    The save slot number to print:

                          * 0 to 7 = print the name of a specific save slot on
                                     the right of the screen

                          * 8 = print the current commander name in the middle
                                column

                          * 9 = print the current commander name in the left
                                column



 Returns:

   A                    A is preserved
