HOW TO GET LADYBUG
------------------
LadyBug is an implementation of LOGO Turtle Graphics. It's features
are listed later in this note.
The LadyBug program takes over 80K on disk; in HEX format ready for
up/down loading it is over 160K. The document is over 140K. At 300
baud it takes 80 minutes or so just for the program. Unless you have
better phone lines than I have, there is no way to go 80 minutes
without at least one hit. Even at 1200 baud with XMODEM protocol, it
is far too large for convenient downloading. As a result LadyBug is
NOT available for downloading on many systems.
Therefore, the best way to get LadyBug is to send me a diskette and a
postage paid mailer. You get LadyBug with documentation on disk.
Please mark LADYBUG on the OUTSIDE of the envelope. Also, please
don't enclose money. LadyBug is NOT for sale. (But see below.)
Send to:
David N. Smith
44 Ole Musket Lane
Danbury, CT 06810
I can also be reached by US mail or EMAIL on CompuServe; my userid
is 73145,153. I would rather that you did not phone me.
LadyBug Requirements
--------------------
LadyBug requires a system with at least:
* 128K of memory.
* One single sided disk drive.
* A graphics adaptor.
* A graphics display of any kind. (Color is supported only on a
color display; 80 column color editing is supported only on a high
resolution monitor.)
* DOS 1.1, 2.0, or 2.1.
* An IBM PC, PCjr, or compatible system. LadyBug directly addresses
the display buffer and thus will not run on some semi-compatible
machines.
A double sided disk drive is needed to copy the distribution diskette.
Single sided drives may be used for execution.
LadyBug Features
----------------
LadyBug is a version of LOGO patterned after the Apple II implementation
developed by Terrapin, Inc. (Apple II is a trademark of Apple, Inc.)
and with additions to make it compatible with many IBM LOGO commands.
Compared with Apple LOGO it has almost:
* All of the graphics commands.
* All of the mathematical computations.
* All of the control commands.
In addition it has:
* A library of procedures adapted from a variety of sources.
* Painting of areas.
* Clipping of drawings (as well as wraparound).
* A fast full screen editor.
* Support for using both displays if both are present.
* Sounds; a PLAY statement and a TONE statement.
The major features missing are:
* List maniputation.
* Variable numbers of parameters to primitives.
* Saving screen images. (Procedures can be saved though).
LadyBug is written in Basic and compiled with the Basic Compiler.
Additions and Changes From Version 0.9
--------------------------------------
The changes made in version 1.0, as compared to version 0.9, include:
* returning values from procedures;
* help key;
* pausing procedures and then continuing;
* SETSCRUNCH to adjust aspect ratios;
* TEST, IFTRUE, and IFFALSE commands;
* some list support;
* some IBM LOGO syntax compatibility;
* expanded limits for the size of procedures, number of lines to
edit, and sizes of constants;
* text screen support;
* tools workspaces; and
* many new builtin functions.
Many smaller changes have also been made. In addition the manual
has been expanded with additional information, examples, and an index.
About LadyBug Distribution
--------------------------
LadyBug is distributed as "User-Supported" software which means that
you do not have to pay for it. You can copy it, give it away, or do
anything else with it except sell it.
If you find that it is very useful, you are invited to make a donation
or contribution to the author of $35. The contribution is voluntary
and in no way should be considered as payment for software or
services.
Under no circumstances should school teachers feel any obligation to
make a donation. One teacher said she has $100 per year for software,
shared between three teachers, and that she would send a donation when
they raised money from selling candy. If that is your kind of
circumstance, please accept LadyBug with my compliments.
Copying by Organizations
------------------------
Educational institutions, clubs, and other nonprofit organizations as
well as individuals are granted permission to freely copy LadyBug and
its documentation and share them with their members or students, or
individuals with their friends, so long as:
* No price is charged for the software or documentation. However,
clubs and other nonprofit organizations may charge a distribution
fee of up to $6 to cover expenses.
* Neither the program nor its documentation are modified in any way
and are distributed together.
Other organizations, and individuals, are allowed to copy LadyBug only
if done without charge and so long as the other rules herein are
followed.
Educational instutitions, clubs, and other nonprofit organizations may
make printed copies of the LadyBug documentation for distribution to
members, or students of the institution, provided that any price
charged does not exceed the actual cost of the duplication of the
copy, and provided that the document is reproduced in its entirety
including all copyright and restrictive notices.
Notice: LadyBug is NOT in the public domain. The author retains
ownership of the program and its copyright.
