    Question msdos arrow keys?

    question: how do i get the arrow keys instead of these shift, alt, and control keys working? i.e. left arrow, right arrow, up arrow, down arrow. help. s.o.s.


    Code:
    
    
    
    
    keyboard=*(unsigned short far*)MK_FP(0x40,0x17);
    
    if(kbhit()){a=getch();}
    
    if(keyboard&0x0002)       
      {              
        // action.
      }
    
    if(keyboard&0x0001)                      
      {
        // action.
      }
    
    if(keyboard&0x0004)
      {
        // action.
      }

    Here is what I did for my maze game that used arrow keys:

    Code:
    		 		
    		if(kbhit())			//if a key is pressed
    		{		            
    			key = getch();	//get the key
    			key_2 = getch();
    			move = (char)key_2; //change it to an int		
    			
    		}
    This below is what you want to do if a certain key is pressed:

    Code:
              if(move == 77)
                 {
                   //do stuff
                 }
    left = 75
    right = 77
    up = 72
    down = 80

    Those are the values for each of the keys.

    Also, this site has a lot of good info on ASCII values.

    EDIT: took out some code that was ony relevant to my program
