A Text Processing System can use a minicomputer and a direct-access storage device (DASD) on which documents are stored in two categories. Permanent storage is used for storing documents until deleted or archived by an operator. Working storage is used for storing documents as they are created and modified prior to being moved into permanent storage. This article describes how DASD storage space can be allocated to minimize DASD storage space fragmentation and how the DASD space allocation can be updated to record the changing circumstances as documents are created or modified.
