I ran the program in debug. The value I got was zero for both up and down keys. I have an ASCII table of values and it did not work when I use it in the program

I´ve done my fair share of PC Assembly, all you need is a screwdriver really...

Right now since I cant figure this out, I am using the w key for up and the s key for down.

Here is a short sample of the code I am using:

Code:

Code

mov ah,01h  ;using 1h so that the program does not wait for key to be pressed, it is only checking to see if it is int 16h ;do the interrupt 	 jz mainloop ;Zero flag is set if no key is pressed  ;go on to check what key was pressed and process input

I found some (rather sketchy) doc that seems to confirm that int 0x16, function 0x01 returns 0 in AL for function keys (http://www.htl-steyr.ac.at/~morg/pci...s/inte1at0.htm).

But it also says that AH contains that key's scan code and I think you should use that if AL is 0. Here is a list of keyboard scan codes: http://www.cs.cmu.edu/afs/cs/user/ra...WWW/files.html (I found it in the part A archive, in the INTERRUP.A file). Also see the INTERRUP.D file for some more info on int 0x16. I will try that, thanks.

I'm quite sure you need to check a second value for function keys like the arrow keys. I don't know assembly at all, but I know that in BASIC and other languages that pick up ASCII for arrow keys, you get a 0 and then another value for keyboards (appears visually with a ^, like ^M for enter).

I just put it into my program and it works perfect.
