David N. Smith's LadyBug
LADYBUG.EXE is the LadyBug program itself. It is written in compiled
BASIC. Run it by entering `LADYBUG' at the DOS prompt.
LADYBUG.LST is the documentation for LadyBug. It contains complete
instructions for the program and an introduction to LOGO and its
ideas. An index is provided.
STATUS.LST contains any information David Smith wishes to add to what is
contained in the manual. STATUS.LST is used to convey news about
recent enhancements to LadyBug or bug reports.
*.BUG is a series of LadyBug procedures. In LOGO, procedures are like
instructions or programs. LadyBug permits you to write your own
procedures and save them to disk.
PROBLEM is a problem report form. David Smith would like you to tell him
of any bugs you discover in LadyBug (apart from the one in the
name).
FRED.EXE is the FRee EDitor, also written by David Smith. It is a simple
and easy-to-use text editor which is closely related to LadyBug's
program editor.
FRED.LST contains additional documentation for FRED. The main part is
found in Appendix A of the LadyBug user's manual, since FRED was
adapted to serve as LadyBug's program editor.
These files contain David N. Smith's LadyBug, a compiled BASIC implementation
of LOGO's Turtle Graphics for the IBM PC. LadyBug requires the
color/graphics adapter and 128K in which to run. (It barely fits on the
PCjr.) If you have a dual monitor system, it permits you to enter
instructions on the monochrome monitor while displaying results on the
color screen.
LadyBug comes complete with a version of FRED, the FRee EDitor as its
program text editor. The user's manual for LadyBug is contained in the
file LADYBUG.LST and is quite complete -- 88 pages!
You run LadyBug by entering "LADYBUG" at the DOS prompt. Novices will find
it convenient to remember that the F1 key interrupts a procedure and
returns you to Command level, where "BYE" causes an exit from the program.
Help screens are also provided. After starting Ladybug, give the command
"LOAD HELP". The Help program will then take over.

This volume is so full that DOS will not fit. In fact, it was not possible
even to reserve space for the hidden system files; therefore even deleting
some of the files presently on disk will not permit transfer of DOS. If
you wish to run LadyBug from a system diskette, you will need to copy the
necessary files to such a disk. The simplest way to make it fit is not to
copy LADYBUG.LST, the documentation file, which is 140K in length.
If you are impatient to try LadyBug, we suggest that you do the following:
1) start LadyBug; 2) type "poly 60 120"; 3) hit F1; 4) type "poly" followed
by any two numbers you like; 5) hit F1 to stop; 6) "bye" will get you out.
David Smith has provided an update file called STATUS.LST which tells you
about any remaining bugs in LadyBug or of any recent enhancements. He also
includes a README file (below) which gives instructions for printing out the
documentation.
LadyBug Version 1.0d (and FRED)
-------------------------------
This disk contains LadyBug, an implementation of LOGO Turtle Graphics
for the IBM PC. It also contains FRED the FRee EDitor. It is a
double sided 8 sector diskette which will work with PC/DOS versions
1.0, 1.1, 2.0, and 2.1. It should work with MS/DOS versions 1.0, 1.25,
and 2.0 on machines which are compatible with the PC but has not been
tested on them.
The files on the diskette are:
LADYBUG.EXE is the program. It is version 1.0c (not 1.0d!)
*.BUG are LadyBug procedures.
LADYBUG.LST is the document.
It should print on virtually any printer. There is no
left margin in the file. Move the paper to the left
1/2 inch or more before printing it. To print:
On any DOS do: COPY LADYBUG.LST LPT1:
On DOS 2.x do: PRINT LADYBUG.LST
STATUS.LST is an addendum to the manual for this version.
PROBLEM is both a problem report form and a mailer for it.
FRED.EXE The FRee EDitor; FRED is sometimes useful in preparing
special input files for LadyBug.
FRED.LST The documentation for FRED.
See the file STATUS.LST for a list of known bugs, manual updates,
and other information specific to this version.
Hardcopy documentation is no longer available. All documentation
is on the diskette.
Despite a lot of testing, it is still possible that you could find
something wrong. I certainly want to know about it so that I can
fix it. If you print the file PROBLEM, you will have both a form
to fill out and an addressed mailer. Just make a quick note about
the problem and drop the form in the mail.
