Abstract

Document/format storage is shared between a base machine and a removable RAM (random-access memory) cartridge. Text storage is shared between a software ROS (read-only storage) cartridge and a feature ROS cartridge. Storage of the documents and formats is protected against system POR (power on reset). A RAM in a base machine and a RAM in a removable cartridge share document storage through each document storage area being discrete in that it can operate independently of the other. To select a document or format in the base machine, only the ID of the document or format is entered. When selecting a document or format in the RAM of the removable cartridge, an "=" sign is entered prior to the ID. Each RAM storage area in the base machine and the cartridge is started on a segment boundary, which has at least 16 bytes.

Software Support for Document and Format Storage in Both Base and Removable Random-Access Memories

Document/format storage is shared between a base machine and a removable RAM (random-access memory) cartridge. Text storage is shared between a software ROS (read-only storage) cartridge and a feature ROS cartridge. Storage of the documents and formats is protected against system POR (power on reset). A RAM in a base machine and a RAM in a removable cartridge share document storage through each document storage area being discrete in that it can operate independently of the other. To select a document or format in the base machine, only the ID of the document or format is entered. When selecting a document or format in the RAM of the removable cartridge, an "=" sign is entered prior to the ID. Each RAM storage area in the base machine and the cartridge is started on a segment boundary, which has at least 16 bytes. This allows the use of common code to reference data in the storage area of either the base machine or the cartridge by simply changing the register to address the RAM area desired. When the system is in a non-record mode in which the written material is not to be stored, a temporary work space always resides only in the RAM of the base machine. This leaves the RAM in the removable cartridge completely available for documents and formats. The sharing of the text storage between a software program in a first ROS cartridge and a feature, such as a program for checking spelling in a second ROS cartridge, is accomplished through enabling access of the second ROS cartridge to the open document in the RAM in the base machine or the remo...
