## Assembly Sources
* Op-code mnemonics must have lower-case letters. The names of instruction macroes may have upper-case letters.
* Op-codes must use their official and commonly used mnemonics, ie bcc and bcs and not bgt and blt
* Hexadecimal number constants should be used except where decimal or binary numbers make much more sense in that constant's context.
* Hexadecimal letters should be upper-case.
