Euphoria 1.0
Public Domain Edition
---------------------

Welcome to Euphoria! ... End User Programming with Hierarchical Objects
for Robust Interpreted Applications

Euphoria is a new programming language developed by Rapid Deployment Software,
a Canadian software research and development firm.

Euphoria is primarily a language for =End User's= like yourself. These are
people who want to develop software for their own use. They want fast,
easy development. They cannot recover the cost of their labor by selling
hundreds or thousands of copies of their programs. They do not want to spend
countless hours debugging. They do not have the time or inclination to
learn a large, complex language intended for professional programmers, but
they need something better than BASIC.

Euphoria is based on =Hierarchical Objects=. If you have heard of the recent
trend toward object-oriented programming, but you still haven't figured out
what all the fuss is about, relax - we aren't talking about objects in that
sense. Euphoria achieves many of the benefits of object-oriented programming,
but in a much simpler way.

Euphoria programs are =Robust=. This means they tend not to crash when used
in unexpected ways. Your Euphoria program will never die mysteriously.
You will always get a full report of what error occurred, where it occurred,
a dump of variable values, and (optionally) a list of the statements that
were executed leading up to the error. Euphoria programs always run with
subscript range checking, uninitialized variable checking, and numerous other
run-time checks in force (although many of these checks are safely
optimized away by the compiler before runtime). These checks catch numerous
errors that would go unnoticed in other languages. Euphoria has dynamic
storage allocation throughout. This saves you a lot of coding time, and
makes programs simpler, with no chance of mysteriously failing just because
the input was a little larger than expected, or a value overflowed 16-bits etc.

Euphoria programs are =Interpreted=. Well, actually they are compiled into
a machine-independent intermediate language and then executed by a
super-high-speed interpreter. Why do we say "super-high-speed"? Try the
benchmark programs in demo\bench. Suffice it to say that Euphoria
is 10 to 15 times faster than Microsoft QBASIC. In benchmark comparisons of
execution speed versus other interpreted languages, Euphoria is always far
out in front. It can actually be a bit *faster* than optimized, compiled C on
some benchmarks. If you find any interpreted language that even comes close
to Euphoria in speed, we would like to hear from you. Languages that compile
to machine code are not able to provide the same level of runtime checking,
flexibility, ease-of-use, and debuggability that Euphoria excels at.

Euphoria is intended primarily for =Applications= programming. It is not well
suited to developing an operating system, or a device driver as these require
intimacy with the hardware. It could certainly be used to write a compiler.
Primarily though, we see Euphoria as a vehicle for quick development of
End User applications.

Some other Features of Euphoria: Euphoria programs do not know or care about
any 640K or 64K memory restrictions for which MS-DOS is infamous. You can use
all of the multiple megabytes of physical memory on your system seamlessly,
and if that isn't enough you can use a swap file on disk to page
chunks of memory in and out based on a least-recently-used algorithm.

Euphoria comes in two different editions: a Public Domain Edition and a
Complete Edition. Both editions will run any Euphoria program of any size at
full speed. The only restriction in the Public Domain Edition is that certain
debugging features are not available for programs larger than 50 executable
statements. Up to 50 executable statements you will have the full support of
the Euphoria debug/trace, profile and all other facilities, and you will get
complete error messages, tracebacks, and dumps of variable values when you
have an error. Note that your program can have an unlimited number of blank-
lines, comments, declarations, "END IF", etc. The standard include files
are also free, provided they have not been significantly altered.

We want you to have fun writing some programs in Euphoria.
When you decide that you like the language and want to develop a large program,
we hope you will decide to purchase the Complete Edition. The Complete Edition
comes with a fully-detailed printed manual for the whole language (meanwhile
see the condensed "mini-manual" in doc\miniman.doc).

You can distribute the Public Domain Edition, without royalty, so anyone
can run a Euphoria program that you have developed. (the Rational Systems
DOS-extender, "dos4gw.exe", required by Euphoria, is also royalty-free.)
However, you may *not* distribute the Complete Edition, in particular the
version of the file "ex.exe" that comes with the Complete Edition.

The Public Domain Edition of Euphoria, in its entirety, is being placed in the
Public Domain. This includes the Public Domain version of the
compiler/interpreter "ex.exe" and all of the demo programs, including the
editor. We encourage you to use it, copy it, distribute it, upload it to BBS's
etc. We are not asking for any shareware registration fee. We hope to make a
modest profit by selling the fully-enabled, Complete Edition of Euphoria, to
those who wish to develop large programs.

We are offering version 1.0 of the Complete Edition of Euphoria for
MS-DOS at the introductory price of just $49.95 Canadian with GST and PST
included! $43.95 in U.S. currency.

To run Euphoria you must have MS-DOS on any 386/486 or Pentium processor.
Euphoria runs quite comfortably on 2 Mb or more of memory. It has been
thoroughly tested under MS-DOS 4, 5 and 6. If the Public Domain
Edition runs on your machine, the Complete Edition will also run.

What's in this Public Domain release:
subdirectory (after installing)
BIN Euphoria (ex.exe) and some useful utility programs
INCLUDE standard .e include files
DEMO games, benchmarks and other Euphoria programs that
you can run to check out Euphoria
DOC documentation files, including a condensed manual


-----------------------------------------------------
-- Read install.doc now to find out how easy it is --
-- to install Euphoria on your hard disk. -- --
-----------------------------------------------------


Try running some of the demo programs in the demo directory.
You can view/modify the source code to any of these demo programs using the
"ed" editor. Then browse the information in the doc directory and start
writing your own Euphoria programs.

... it's time to get euphoric!
