GRAPHICS PROGRAMS ON GRAF0001
LADYBUG VERSION 1.0
LadyBug is a version of LOGO patterned after the Apple II
implementation developed by Terrapin, Inc. It was written as
an introduction to LOGO and Turtle Graphics. The author
recommends that those with a serious need for LOGO use a
commercial version because it is not as well documented and
will not perform as well as a good commercial LOGO. All
Ladybug documentation is on the diskette.
In general it has almost:
* All of the graphics commands.
* All of the mathematical computations.
* All of the control commands.
In addition it has:
* A large library of procedures adapted from a variety of
sources.
* Painting of areas.
* Clipping of drawings (as well as wraparound).
* A fast full screen editor. (FRED)
* Support for using both displays if both are present.
The major features missing are:
* List maniputation.
* Variable numbers of parameters to primitives.
LadyBug is written in Basic and compiled with the Basic
Compiler.
FRED -a very easy to use editor.
