推荐答案

为什么要尝试通过我不知道的IBM 360系列测试?像我的手表一样强大的处理能力，他们在20世纪70年代或80年代初就不再生产它们了.

但是，这是您的测试，因此您应该自己学习，而不是仅仅吃汤匙: http://zh.wikibooks.org/wiki/360_Assembly/360_Instructions [^ ]
或: http://www.bixoft.nl/english/oplist.htm [

Why you would be trying to pass a test on the IBM 360 series I don''t know - they had about as much processing power as my watch does, and they stopped making them in the ''70s or early ''80s...

However, it''s your test, so you should learn it for yourself, rather than just getting spoon fed: http://en.wikibooks.org/wiki/360_Assembly/360_Instructions[^]
Or: http://www.bixoft.nl/english/oplist.htm[^]

For example, the second site will tell you that BALR is basically a subroutine call, and give you a full explanation.
