| 术语 | loop box |
| 释义 | loop box 循环变址器 A specific register used as an index register but only to modify instructions immediately prior to their execution. For example, a number or symbol is added to an instruction as the last step before the instruction is executed and the instruction is thus modified, but without changing the instruction as it is stored in memory. 用作变址寄存器的一种专用寄存器, 但只在指令马上执行前修改指令。例如,数字或符号加到指令上,作为指令执行前的最后一步,指令就被修改了,但是没有改变指令本身,因为指令是存在存储器中的。 |
