Abstract

The Set Program Mask instruction, SPM, is used to change the 2-bit condition code and 4-bit program mask in the current PSW. Before executing SPM, you should set bits 34 and 35 of general register R1 to the desired value of the condition code. You should also initialize bits 3639 of general register R1 – these values will replace the program mask. Bits 0-33 and 40-63 of general register R1 are ignored. Here is an example:

设置程序掩码指令SPM用于改变当前PSW中的2位条件码和4位程序掩码。在执行SPM之前，应该将通用寄存器R1的第34位和第35位设置为条件码的期望值。您还应该初始化通用寄存器R1的3639位-这些值将替换程序掩码。一般寄存器R1的0-33位和40-63位被忽略。下面是一个例子:
