摘要：In a data processing network having a first processor (for example, a

programmable workstation), a second processor (for example a host computer) and acommunication system linking said first processor and said second processor, controllogic associated with said first processor is operable to manage the flow of informationbetween said first processor and said second processor on behalf of one or moreapplication programs running on said first processor. The control logic is responsive tocalls issued by, or on behalf of, an application invoked by a user at the first processor todetermine if a file or, set of files, associated with the calling application is the most up-to-date version of the file, or set of files available. The most up-to-date versions are alwaysstored at the second processor (i.e.: the host). A comparison is made between the filesand their levels currently available at the first processor (work station) and the up-to-date files held at the second processor (host). A list of actions to be taken is thencompiled and files downloaded to the first processor to replace out-of-date files, to addor create files in order to augment those already there, and to delete any obsolete filesno longer required by the application.
