Abstract

A way is described to move a large block of text within the Notewriter work space without using up an equally large block of extra memory. Notewriter is a mini-application that provides a way for the user to create, save, and edit simple notes. The size of a note is limited to about 12K bytes of memory or about 7-8 pages of text. Notes may be saved and retrieved from diskette as standard ASCII files using IBM PC-DOS file-naming conventions. Full-screen editing support is provided for the user to insert or delete characters, lines, and blocks. A method of doing block moves in a way that conserves memory by using memory that is already available is described. (Image Omitted) The Notewriter mini-application is designed to run in a minimum amount of RAM storage.
