SET   - Set Condition Instruction

The SET instruction sets a flag condition in an 8 bit Register or a memory address.
This command has 2 parts, Instruction, then either a Register, or a memory address.

Many of these SET Instructions have the same or similar effects and therefore share the same Op Code.

• O = Overflow Flag
• C = Carry Flag
• S = Sign Flag
• P = Parity Flag
• N = Not that action
• E = Equals
• L = Lower than
• G = Greater than
• Z = Zero value
• A = Above
• B = Below

Syntax: SET.. 0x03 or SET.. AL etc.
