ABSTRACT:
A document manager controls the loading into memory from a mass storage means, such as a disk, a document file in disk file format. The loaded document file is stored in memory in document structure format for subsequent access thereto by a task, such as an application program. The loading of the document file into memory may be initiated by a task, either as a result of a user command or as a result of the operation of the task itself. In response to a request to load a document file, the document manager makes a request of a memory manager unit for an assigment of memory space to store the document file. After storage of the document file within the assigned memory space the document manager generates within the memory a document control block descriptive of various parameters associated with the loaded document. The document manager subsequently writes the location within memory of the generated document control block into an assigned location within the task requesting access to the document file. The requesting task is thereby enabled to gain access to the loaded document file.
