==Assembly Instruction Set for Taylor using CustomASM==
* REGs are A, B, C, D, E, F, G, and H (0-7 respecitvely)
not to be confused with
* Instruction A, B, and C, which can represent ":REG" or a ":FLAG", their value can range from 0x0 to 0xF(15)
* IMM is a Intermediate Value, can be anything from 0x0000000 to 0x7FFFFFF
* / means continue reading same spot 1 line up
