    *  file d:\cips\mymsc.c
    *
    *  Functions: This file contains
    *     my_clearscreen
    *     my_setvideomode
    *     my_setlinestyle
    *     my_setcolor
    *     my_setpixel

    *     my_remappalette
    *     my_map_64_shades_of_gray
    *
    *  Purpose:
    *     This file contains subroutines that 
    *     call Microsoft C 6.0 specific 
    *     routines.  I put them all here in one
    *     file to make it easier to port the
    *     C Image Processing System software
    *     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.
    *
    *  External Calls: all MSC calls
    *     _clearscreen
    *     _setvideomode
    *     _setlinestyle
    *     _setcolor
    *     _setpixel
    *     _moveto
    *     _lineto
    *     _settextcolor
