Latest Patents

Bachman holds a patent for a "System for protecting shared files in a multiprogrammed computer." This invention presents an arrangement for sharing file information among multiple processes within a multiprogrammed computing system. The source program file declarations are compiled into file control structures, which are organized into skeletal segments. These segments form units of potential sharing between active processes. Depending on the declared sharing level of the file, segments containing file control structures are placed in the address space of all processes, related processes, or a single process. The job control language (JCL) commands are expanded into JCL file control structures and merged with the source language structures to create a file request control structure. This request is then compared against a catalog of existing external files, ensuring that the account requesting file assignment is authorized to access the file. Further tests are conducted to guarantee compatibility between the request and the current status of the file.
