Hey guys i just joined, I am sure this is a dumb question, but i been googling for the past week and cant seem to find a simple answer. I been trying to learn asm and I am trying to make a menu system. So like you type 1 and it jumps to that, you type 2 it jumps to that and so on. I cant seem to find out how to get user input though. Sorry if the answer is already on the forums I cant seem to find it.
Thanks for you help.

What OS are you using?
If it is x86 google "dos interrupt 21h".
If you are on a MIPS processor you'll need to google "mips syscall".
Hope this helps.

Also what assembler because some assemblers have macros that do all (or most) of the grunt work of calling system functions.

You mean you actually boot linux from a CD
You must be awfully patient to wait all that time for your computer to boot up. •

Its not a compiler, but an assembler.

you need a good explaination of those interrupt functions. Here is just one of them you can find. Function 1, which you posted, only tests to see if a key has been pressed. You have to call other functions to actually get the value, such as function 10. But it too only returns the value of ONE key, so you have to create a loop and keep calling those two functions until function 1 says no-more-keys.
what you do with those keys is up to you -- normally you will want to put then into a buffer so that they can be easily used whenever you want.

EXAMPLE
