escape to CP

In VM／370, a transfer of control to CP when either the terminal user or the machine stops virtual machine operation. This can be accomplished by a CP com- mand (such as CP), by invoking a DIAGNOSE function, or by signalling attention.; 在IBM的操作系統VM／370中,當終端用戶或機器停止虛機操作時,CPU控制權向CP轉移的 過程。用一條CP命令(如CP),或調用DIAGNOSE操作程序,或發出一個引起注意信號,就可以 實現這種過程。
