First Claim
Patent Images
1. A method of facilitating input/output processing of a processing environment, said method comprising:
- obtaining by an input/output communications adapter of the processing environment a transport control word, said transport control word specifying a location in memory of the processing environment that includes a plurality of input/output commands to be executed and a location in memory for status information relating to execution of the plurality of input/output commands;
forwarding from the input/output communications adapter to a control unit of the processing environment the plurality of input/output commands as one entity; and
executing by the control unit the plurality of input/output commands to perform one or more input/output operations, wherein the executing is performed absent a tracking by the input/output communications adapter of state relative to the individual input/output commands of the plurality of input/output commands being executed by the control unit.

Abstract
Input/output processing is facilitated by readily enabling access to information associated with input/output processing. This information includes status information and measurement data provided by a control unit executing input/output commands. The status and measurement data are provided in a status control block identified in a transport control word, which is further used to specify a location in memory that includes the input/output commands to be executed.
