Sedt Version 1.1(18)
Author: Anker Berg-Sonne
Description
Sedt is a screen editor written with the goal of
providing a common editor across a wide range of operating
systems. Sedt is for ease-of-use programmed with a keyboard
layout similar to EDT.
Sedt provides a wide range of features that other than
standard EDT. Examples are multi-windowing and marks.
Sedt's most spectacular feature is the terminal
performance, which makes Sedt viable as the standard editor on
systems where EDT severely affect system performance.
Distribution Policy
Sedt binaries are being made available for customers and
Digital internal use on the condition that the original copyright
is not violated or removed, that no modifications are made to
the program, and that Sedt is used only on Digital CPUs.
Sedt sources are only made available to Digital
employees, and on the condition that the original copyright is
not violated or removed and that extentions or modifications are
returned to the author. An exception is the module TERM.C and
the .H files necessary to compile TERM.C. These and all object
files may be distributes freely to facilitate adapting Sedt to
other terminals.
Sedt may only be distributed in a form that precludes
the use on non-Digital CPUs, but may be modified to work on
other operating systems and terminals.
Original versions of Sedt are defined as being copies
identical to one produced by the author, and may only be
distributed in the original form with no changes made to either
sources, binaries or data files.
Modified versions of Sedt must be clearly labeled as
such, and must identify themselves as such when run. The sources
must clearly identify the origin and areas of modification.
Modifications must be made in the spirit of the original
version, preserving the performance goals and coding standards
of the original.
Across all operating systems Sedt is designed to produce
identical output the screen after completing identical commands
on identical source files, thus being functionally identical
across all operating systems. To the extent that the operating
systems make this possible, this design goal must be implemented
in all modified versions.
Installation Instructions
CP/M and MS/DOS
Sedt will run on MS/DOS under AME86 in CP/M emulation
mode.

Sedthelp.Wps from the Sedt disk and rename them to be
Sedtkeys.Txt and Sedthelp.Txt.
Installation Instructions
VMS
Copy Sedt.Exe, Sedt.Com, Sedtkeys.Edt, Sedtkeys.Wps,
Sedthelp.Edt, Sedthelp.Wps, Sedtman.Edt to a directory. Define
the logical name Sedt$Dir to point to the directory, the symbol
Se*dt:==$Sedt$Dir:Sedt and KSe*dt:==@Sedt$Dir:Sedt.
If you use the EDT keypad define the logical names
Sedt$Keys to be Sedt$Dir:Sedtkeys.Edt and Sedt$Help to be
Sedt$Dir:Sedthelp.Edt.
If you use the WPS keypad define the logical names
Sedt$Keys to be Sedt$Dir:Sedtkeys.Wps and Sedt$Help to be
Sedt$Dir:Sedthelp.Wps.
