      According to the Microsoft "MS-DOS Programmer's Reference",   
   Version 5, loading a *.COM program needs to allocate memory   
   to load the program, plus 256 bytes for the PSP, and 256 bytes   
   for the stack.  If it does not have that much memory it refuses   
   to load the program.  And the program, PSP, and stack must fit   
   into a 64k segment.
