here is the finction.  it is the part of a 'scrolling window' that
displays the messages, and scrolls them.
the locate(x, y) function moves the cursor on the screen to column x,
and row y. the clrreset() function resets the text colors.


void msginput(char *msg) /* NEEDS WORK */
{

int x = 0; /* used as a loop counter */
char msg1[78]; /* always contains line 1 */
char msg2[78]; /* always contains line 2 */
char msg3[78]; /* always contains line 3 */
char msg4[78]; /* always contains line 4 */

   textcolor(3); /* set color to cyan */

   if(count==0) /* print on the top line */
   {
      strcpy(msg1,msg);
      locate(2,19);
      cprintf("%s",msg1);
      locate(2,20);
      count++;
   }
   else if(count==1) /* print on the second line */
   {
      strcpy(msg2,msg);
      locate(2,20);
      cprintf("%s",msg2);
      locate(2,21);
      count++;
   }
   else if(count==2) /* print on the third line */
   {
      strcpy(msg3,msg);
      locate(2,21);
      cprintf("%s",msg3);
      locate(2,22);
      count++;
   }
   else if(count==3) /* print on the fourth line */
   {
      strcpy(msg4,msg);
      locate(2,22);
      cprintf("%s",msg4);
      count++;
   }
   else if(count==4) /* move everything up a line, and print the newest
line */
   {
      strcpy(msg1,msg2); /* recopy all the strings */
      strcpy(msg2,msg3);
      strcpy(msg3,msg4);
      strcpy(msg4,msg);

      locate(2,19);
     
cprintf("                                                                             
");
      cprintf("%s",msg1);
      locate(2,20);
     
cprintf("                                                                             
");
      cprintf("%s",msg2);
      locate(2,21);
     
cprintf("                                                                             
");
      cprintf("%s",msg3);
      locate(2,22);
     
cprintf("                                                                             
");
      cprintf("%s",msg4);
      locate(2,22);

   }
   clrreset();
}
