I've been messing around in assembly. I noticed that the command INT 12h gets the ammount of RAM and stores it in kbs. Now I've been trying to write a program which gets the amount of RAM and displays it but I can't seem to find a way of doing that. Could someone explain to me how I would display the results of 12h?

P.S. As you probably have noticed I'm a complete newbie to assembly. I saw some code for finding the ram size and being me I started messing with it to try and find a way of throwing it back at me.

If the number is in kilobytes, you'll need to multiply it by 1024 to get the amount in bytes. To print the result, you'll need a hex2ascii routine (e.g., see thread below):
