A software architecture at a target computer is provided in which it is desired to trigger execution of target processes by an agent process which receives operation specifying data which has been autonomously generated by an initiating computer. The recording method includes recording a recording unit block in which invalid data is padded in part of the block and recording padding information indicating that the invalid data is included. The character recognition module recognizes character codes corresponding to handwritten characters in a first line and a second line which follows the first line. An electrically conductive portion of the shaft is concentrically located substantially within the vacuum bellows and electrically insulated therefrom and is configured to receive and conduct a signal. During the prefetching, the prefetching is adjusted as changes in the prefetch depth are detected. An electromagnet, which may be remotely actuated, is utilized selectively counteract the magnetic restraining force and allow the latch assembly to open and release the second object.
