    • An adaptive data transfer channel providing means for a data management access method (AM) to define the channel subsystem data block transfer size and to transfer an extended data block (EDB) by a single channel transfer command to avoid repeated channel command word (CCW) command decode and status presentation operations. The adaptive scheme of this invention is transparent to the user and downwardly compatible with existing data record storage formats because it is independent of the user application program. The host software in the central processing complex (CPC) tests the peripheral data storage device (PDSD) to ensure compatibility with the EDB CCWs before selecting the channel program (CP) to be used for data block transfer in the subchannel. In the EDB format, the PDSD microcode permits the accumulation of logical data blocks (LDBs) from storage to form a single large EDB before transfer to the CPC responsive to a single transfer command. Conversely, the CPC can transfer a single EDB to the PDSD where it is parsed to form data records in an existing data record storage format, thus ensuring complete downward compatibility with existing data record storage formats.
    • 一种用于数据管理访问方法(AM)的自适应数据传输信道提供装置,用于定义信道子系统数据块传输大小并通过单个信道传送命令传送扩展数据块(EDB),以避免重复的信道命令字(CCW) 命令解码和状态显示操作。 本发明的自适应方案对于用户是透明的,并且与现有数据记录存储格式向下兼容,因为它独立于用户应用程序。 在中央处理复合体(CPC)中的主机软件测试外围数据存储设备(PDSD)以确保与EDB CCW的兼容性,然后选择用于在子信道中进行数据块传输的通道程序(CP)。 在EDB格式中,PDSD微码允许在存储之前积累来自存储器的逻辑数据块(LDB),以在响应于单个传送命令传送到CPC之前形成单个大的EDB。 相反,CPC可以将单个EDB传输到已解析的PDSD,以形成现有数据记录存储格式的数据记录,从而确保与现有数据记录存储格式完全向下兼容。
