Loading/Running Binary Programs

[PearOs]

Hey guys, I am at the point in my 64bit Assembly Operating System, where I would like to write programs in Assembly and load and run them. So my question is how do I go about this for kernel calls and calls to other parts of code? For example, I have an Asm class called "Console" and a call would be "Console_Print", in lets say "hello.asm" which is compiled down to "hello.app" and is a binary file using Nasm, how do I call "Console_Print"? I don't know the address to it, so that's where things get tricky. Anyways thanks for the help! - Matt
