union REGS mouse; 

int across;                  /* horizontal position of paddle */

mouse.x.ax = 0x0B;           /* initialise to tell BIOS what info required   */
int86(0x33, &mouse, &mouse); /* ask how far the mouse moved since last look  */
mdy=mouse.x.cx;              /* the vertical mouse movement returned in cx   */
across+=mdy;                 /* add / remove movement from 'across' variable */
