    • Characters of data on a document are recognized by automatically determining the definitions of characters of the data from the arrangement of character strings of the data. Character strings on the document are extracted by reading the document, and headers and data on the document are distinguished from each other by determining the positional relationship between the character strings. Character attributes of the data are determined by recognizing characters of the character strings of the headers using a header recognition dictionary. Characters of the character strings of the data are recognized according to the determined character attributes of the data. Since character attributes of the data are determined from recognized characters of the headers after the headers and the data are distinguished from each other from the layout on the document, it is possible to enter automatically the character attributes of the data.
    • 通过从数据的字符串的排列自动确定数据的字符的定义来识别文档上的数据的字符。 通过读取文档来提取文档上的字符串,并且通过确定字符串之间的位置关系来区分文档上的标题和数据。 通过使用标题识别字典识别标题的字符串的字符来确定数据的字符属性。 根据确定的数据的字符属性来识别数据的字符串的字符。 由于数据的字符属性是从头文件的标识符和数据从文档的布局彼此区分开来的识别字符确定的,所以可以自动输入数据的字符属性。

    • A dynamic address translation system for use in a channel or sub-system adapter, wherein the main memory of a system is used in common with a central processing unit.The system provides registers for storing a copy of an entry within the address translation table in the main memory and a bit which indicates the validity of such a copy, and when the central processing unit has issued an instruction for updating the entry within said address translation table or an instruction to alter said entry, the bit which indicates the validity of the contents of said register, is changed so as to indicate invalidity of the associated register contents. It is unnecessary in this system to fix the page in the main memory prior to execution of channel programs.
    • 一种在通道或子系统适配器中使用的动态地址转换系统,其中系统的主存储器与中央处理单元共同使用。 该系统提供用于存储主存储器中的地址转换表内的条目的副本的寄存器和指示这种副本的有效性的位,并且当中央处理单元已经发出用于更新所述地址转换中的条目的指令 表或改变所述条目的指令,指示所述寄存器的内容的有效性的位被改变,以指示相关联的寄存器内容的无效。 在执行频道节目之前,该系统无需将主页面固定在主存储器中。

    • In an inter-subsystem communication system which has a communication queue enqueued by one subsystem having processors and dequeued by another subsystem having processors, there is provided between the subsystems direct memory access means which permits either of the subsystems to directly access a memory of the other subsystem, and in a queue element enqueued by the one subsystem is inserted memory access control information necessary for accessing the one subsystem, whereby a high-grade function is performed by the plurality of subsystems. When the source subsystem issues an enqueue command, the queue element length of a queue element produced in response to the queue command is compared with a remaining space of the queue and, if the comparison result satisfies a predetermined condition, an overflow interruption is caused in the processor of the source subsystem, thereby to efficiently detect a queue overflow state or queue usable state.
    • 在子系统通信系统中,具有由具有处理器的一个子系统排队的通信队列并由具有处理器的另一个子系统排队的子系统间通信系统,在子系统之间提供直接存储器访问装置,其允许子系统之一直接访问另一个的存储器 子系统,并且在由一个子系统排队的队列元素中插入访问一个子系统所需的存储器访问控制信息,由此由多个子系统执行高级功能。 当源子系统发出入队命令时,将与队列命令对应的队列元素的队列元素长度与队列的剩余空间进行比较,如果比较结果满足预定条件,则会导致溢出中断 源子系统的处理器,从而有效地检测队列溢出状态或队列可用状态。
