QED is a powerful text editing program for use with NORD computers.

It is primarily designed for maintaining multiple language source program files, such as MAC, NORD PL, FORTRAN or BASIC, though its convenience and ease of usage makes it suitable for all kinds of text editing.

The text being edited may be read from and written to any mass storage file or I/O device and text lines may be added, modified, replaced and deleted by a few easy-to-learn commands.

Lines of text may be addressed in several ways to make it easy for the user to position a specific line or a collection of lines where editing is to be performed. Positioning to a particular line may be specified in the commands themselves; however, just a line address itself can be a command to cause positioning to occur.[1]

QED is a re-implementation of the editor of the same name originally created by Butler Lampson and L. Peter Deutsch (of Ghostscript fame), by Bo Lewendal at Norsk Data. It was originally implemented for the NORD-1 in 1971. This according to an ND employee who watched it happen at the time.[2]

Product number

QED is part of ND-210400 subsystem package II.
