Xspread is an electronic spreadsheet which runs under X; it was developed by
software engineering teams as part of a college course "Introduction to
Software Engineering".  The structure and operation of the spreadsheet is
similar to but not identical with popular spreadsheets such as Lotus 1-2-3
and its clones.  Like other spreadsheets, the workspace is arranged into rows
and columns of cells.  Each cell can contain a number, a label (i.e.
character string), or a formula which evaluates to a number or label.
Xspread is apparently based on sc. Sources are available as

The GNU package Oleo handles spreadsheet cells with cross-references and
calculation formulas.  It can generate PostScript renditions of
spreadsheets.  Sources are available

Wingz is an easy-to-use, graphical spreadsheet for business and technical
professionals, that allows users to create sophisticated presentations and
reports, as well as user interfaces and end-user applications.  The next
major release of Wingz (version 2.1) is currently in beta and 
the 1.4.1 release is being released for Linux as shareware. Wingz 1.4.1
for Linux is a fully functional release of Wingz 1.x and as such is fully
compatible with all other non-realtime versions of Wingz 1.x.

NExS, the Network Extensible Spreadsheet from X Engineering Software Systems,
is a full-featured, Motif compliant spreadsheet developed specifically for
Unix.  A complete application programming interface (API) is provided with
NExS. The API allows external processes, running locally or remotely, to
access and manipulate the formulas and data stored in NExS cells, as well as
access to all of the controls and features of NExS, including graphics. The
flexible NExS API allows the NExS spreadsheet to serve as either the "client"
or the "server" in a networked environment, supporting one-to-many,
many-to-one, and many-to-many connectivity.  You can download the functional
demonstration of NExS which may be enabled for a full license; it is
available from http://www.xess.com/ . [6/96]
