摘要： Provides a dynamic execution link between an analyzer program and each hook instruction in a program. Special types of hook instructions are provided for use in a hooked program. The link causes the analyzer program to execute as part of a continuous uninterrupted execution for each hook instruction. The link uses hardware and/or internal code to access a hook control area which provides linkage information needed to invoke the execution of the analyzer program upon completion of the hook instruction and to continue the execution of the hooked program following the completion of the analyzer program. The linkage information includes the entry location into the analyzer program, and also locates the first hook work area (HWA) of a sequence of HWAs, from which an HWA is assigned to each current hook instruction. The assigned HWA stores a return point location in the hooked program at an instruction following the current hook instruction. One or more hooked programs may concurrently use the same analyzer program. As soon as execution by the analyzer program ends for a hook instruction, its assigned HWA is released for use by another hook instruction.

摘要： Enables an I/O channel program to use IDAWs (indirect data address words) to control data transfers from/to an I/O (input/output) device to/from either or both of ES (expanded storage) and/or system MS (main storage), in which data moved to/from ES does not move through MS. ES and MS are plural electronic storage media in a data processing system, and the I/O device is any I/O device selectable by the system. Intermixing of data transfers between ES and MS may be controlled by a single IDAW list accessed by a channel control word (CCW) in a channel program in a data transfer direction indicated in the CCW without any channel mode change.
摘要翻译：启用I / O通道程序以使用IDAW（间接数据地址字）来控制从I / O（输入/输出）设备到/从ES（扩展存储）和/或系统MS之一或两者的数据传输（主存储），其中移动到/从ES的数据不通过MS移动。 ES和MS是数据处理系统中的多个电子存储介质，I / O设备是可由系统选择的任何I / O设备。在ES和MS之间的数据传输的混合可以由在CCW中指示的数据传送方向上的信道程序中由信道控制字（CCW）访问的单个IDAW列表来控制，而没有任何信道模式改变。
