Indefinite Page Length

Merge operations, number of lines, etc., productivity restrictions are eliminated by removing page length limitations normally tied to the capacity of a working buffer.

Modern flexible, economic, and efficient keyboard/display word processing systems universally have one item in common. This is a limited capacity working text storage buffer. The character capacity of the buffer corresponds roughly to that of a tightly packed printed page. The major advantages of a limited capacity buffer are real time accessing and low costs. Major disadvantages are a small amount of readily accessible text, and reduced function and operation capabilities.

Consider, for example, an 8,000-character text storage buffer. For the majority of letter applications which involve a single page of text, essentially no operation restrictions exist. However, the capability of handling a single spaced, legal size page of 12 pitch characters with wide margins is questionable. This is because the capacity of the buffer can be exceeded. When the buffer becomes full, merge operations are impossible.

The above noted problems are overcome by (1) defining pages through coding (page end codes, etc.) without regard to length or buffer capacity, and (2) providing for automatic transfer between the buffer and a bulk store, such as a floppy disk. Hardware capabilities already include the ability to transfer text between the limited capacity buffer and a bulk store. As such, only sync points, such as buffer full, buffer empty, etc., need now be defined for automatic text transfer operations. With this arrangement, the trade-off is cost and flexibility for rea...
