Macros

Macros are a very powerful way to extend Assembly instructions. In a good Assembler, macros even allow you to write your own high-level language!

---

Advantages:

• Runs at full processor speed, without layers, interpreters, or libraries
• Can be used as plain inline code, or as a command generating just a call to a function you define
• If used as inline code, it can be used for code folding
• Allows optional parameters (also available in most but not all high-level languages)
• Allows the dynamic generation of large sections of code or data tables, using mathematical formulas

This section will contain examples and tutorials on how to use macros to best effect.

How about this assembler program? :)
