    *     to other C compilers and non-IBM PC
    *     computers.
    *
    *     Each subroutine in this file is a "wrapper"
    *     for a Microsoft C 6.0 routine.  I put
    *     the letters "my" in front of the Microsoft
    *     routine name.  For example, my_clearscreen
    *     calls Microsoft's _clearscreen.
    *
    *     The one exception is
    *     my_map_64_shades_of_gray.
