In addition....you never specified what assembly language you need help in. How is anyone supposed to help you?

Recursively or iterively should have been your first specification. Nobody is just going to give you code to "study" from and "attempt to write" the same thing (or similar). Sound fishy to you?

Is there a way to recognize when a key is pressed in 32-bit masm? I know you can use interrupts in 16 bit, but how can this be done using 32-bit, since 32-bit is protected by the OS.

Thanks,
