在根本指令和功用指令执行中，用一个仓库寄存器暂存逻辑操作的中心结果，仓库寄存器有9位（如图1所示），按先进后出、后进先出的原理工作。当前操作结果压入时，仓库各原状况悉数左移一位；相反地取出操作结果时仓库悉数右移一位，终压入的信号首先恢复读出。
There are two kinds of instructions in fanuc-pmc-l: basic instructions and functional instructions. When planning the sequence procedure, the basic instructions are used most, and there are 12 basic instructions in total. The function instructions are convenient for the programming of special operation and control of the machine tool. There are 35 function instructions.
In the execution of basic instructions and function instructions, a warehouse register is used to temporarily store the central result of logical operations. The warehouse register has 9 bits (as shown in Figure 1), and works according to the principle of first in last out and last in first out. When the current operation result is pressed in, all the original conditions of the warehouse are moved to the left by one bit; On the contrary, when taking out the operation results, the warehouse moves all to the right by one bit, and the final pressed signal is first restored to be read out.
