I was reading a book the other day on assembly. I reached the chapter on interrupts and I got up to the DOS interrupt int 21h. I use it and now I have been playing around with it, but as I continued to read it said that this feature, although accessible, is out of date and you should use alternatives. My Questions are:

Is int 21h still used?
If there is an alternative, what is it?

I am using x86 and the FASM and MASM assemblers.
