• EQUate. Give a constant a name.
• SET. Same as EQUate but with a subtle difference. You can change the value of a SET during assembling.
• Structures (the RS group). Define a structure easily.
• String equate (EQUS). Give an often used string a name. Can also be used as a mini-macro. Much like #define in C.
• MACROs. A block of code or pseudo instructions that you invoke like any other mnemonic. You can give them arguments too! Life is good.
