actual instruction
Computing term for an instruction that is actually executed by the processor, as opposed to a symbolic or pseudo-instruction.
In assembly language, it is necessary to distinguish between actual instructions and pseudo-instructions.
疑似命令 is a pseudo-instruction that is not directly executed but directs the assembler, while 実効命令 is an actual machine instruction.
Compound of 実効 (actual effect) and 命令 (instruction). The exact historical derivation is uncertain; the term is used in modern computing contexts.
