Expressions.lha is an additional archive to use with "Oberon System V4
for Amiga V1.4". You need the main archive Oberon.lha to run this.
Extract this archive into the same directory where you extracted
Oberon.lha .

------------------------------------------------------------------------------

Expr is a package for editing and displaying mathematical expressions within
text documents and for interfacing mathematical software.

This software is a research prototype only. No warranties can be assumed.

Currently, the code is available for SparcOberon, SolarisOberon, MacOberon,
DecOberon, Oberon for Windows, and Oberon for Amiga. (Many thanks to
Ralf Degner for compiling the Oberon for Amiga version!)


Further, several documents are provided:

ExprUsage.Text       introductory user's guide (please read this first!)
Expressions.Tool     lists most important commands and documents
ExprPalette.Text     palette with some Extensions
ExprDemo.Text        some example expressions


For all environments except for SolarisOberon a link to the Maple computer
algebra system is provided. This component also includes some communication
facilities it requires (and a terminal emulation). To use Maple it needs to
be accessible on a unix machine via (r)login. 
Information documents:

ExprMaple.Text       introductory user's guide to maple interface
ExprMaple.Tool       commands used for maple interface
MapleFormManip.Text  demonstration text for an interactive document


If you want to program and extend the framework you will find the needed
information in this documents:

ExprProgramming.Text
ExprBessel.Mod
ExprSubstituter.Mod


Please send any questions or comments via e-mail to weckinf.ethz.ch .
