A large part of assembly language programming, especially in the beginning, consists of translating high level language structures into corresponding snippets of assembly language code. The Joy of Coding gives a quick reference, mapping ``what you want to do'' to ``how does an HC11 do that.'' Its main purpose is to provide you with a series of templates that you can combine to build an assembly language program. In order to find details on how the referenced instructions work, you'll need to go to the manuals.

This page will be growing throughout the semester, as we encounter more and more situations that deserve inclusion into the Joy.
