Jumps unconditionally to a memory address. Sets the Program Counter to Address.
\section{JZA (Jump to Address if Zero)}
\OpcodeTable{0x20}{jza}{Address}{None}\\[6pt]
Jumps to a memory address if the status flag is zero.
\section{JGA (Jump to Address if Greater Than)}
\OpcodeTable{0x70}{jga}{Address}{None}\\[6pt]
Jump to the Address if the status flag is greater than zero.
\section{JLA (Jump to Address if Less Than)}
