In a computer instruction set architecture (ISA), an execute instruction is a machine language instruction which treats data as a machine instruction and executes it.
It can be considered a fourth mode of instruction sequencing after ordinary sequential execution, branching, and interrupting.[1] Since it is an instruction that operates on other instructions like the repeat instruction, it has also been classified as a meta-instruction.[2]
