Subj: Instructions for FTP receipt of Project CALC Mathematica labs.
It is now possible to obtain the Mathematica labs produced at Bowdoin for
Duke University's Project CALC program via anonymous ftp. This document
tells you how this is done. If you are unable to use this method and would
prefer to receive the labs on disks via ordinary mail, send me such a
request.
Currently Release 6 of our materials has been placed in the ftp area.
Detailed descriptions of the contents of this release will be found in the
document rel6-ReadMe. Release 6 contains the versions of the laboratory
notebooks that were current as of mid-February. All are fully compatible
with Mathematica v2.1
Laboratories 31 through 37 are currently posted in "preliminary form."
Revision of these notebooks will be complete by the end of April, and the new
versions will be posted in the "revisions" directory in our ftp area. Those
of you interested in having the most current versions of our labs and
packages should check this directory on a regular basis.
If you wish to receive information from us on a regular basis, please send a
request asking to be placed in our "Dissemination Network." Currently
printed versions of the first and second semester labs can be obtained from
D. C. Heath (the publisher for all Project CALC materials) in the form of a
laboratory manual (preliminary version). The third semester labs will also
be available in this form by the fall.
Versions of our laboratories that were current as of September 1992 are
available for NeXT computers. (This would be essentially Release 5+.) These
notebooks will be found in the "NeXT" directory in our ftp area, along with
further information on converting notebooks from one hardware platform to
another.
What follows is a sample ftp session along with some explanatory comments;
this should enable you to obtain any currently posted file.
I wish to thank my colleague Steve Fisk for designing and setting up this ftp
directory.
Note: For those of you who need it, the Bowdoin's numerical Internet address
is 139.140.1.1.
----------------------------------------------------------------------------
Log on to a computer with Internet access and enter
ftp polar.bowdoin.edu
You will be answered by the following statements:
Connected to polar.bowdoin.edu.
220 polar.bowdoin.edu FTP server: ready.
Now login with the username 'anonymous' and
your e-mail address as the password.
Name (polar.bowdoin.edu:): anonymous
331 Guest login ok, send ident as password.
Password:your-e-mail-address
230 Guest login ok, access restrictions apply.
You now can connect to the appropriate directory. Depending on what you wish
to receive, the last phrase in the directory name will be either
release-6, revisions, or NeXT.
ftp> cd pub/calculus/release-6
250 CWD command successful.
You now can ask for a list of what is in the directory
ftp> dir
200 PORT command successful.

To transfer an individual file use the following command:
ftp> get rel6-ReadMe
To transfer all the contents of the current directory use the commands
ftp> mget *
mget rel6-ReadMe? yes (you will be asked about each file)
To change to one of the other directories use the commands
ftp> cdup
250 CWD command successful.
ftp> cd ./revisions
To quit:
ftp> quit
--------------------------------------------
Once the desired files have transferred to your Internet-connected computer,
the ReadMe files can be opened immediately. The remaining files must be
transferred to a Macintosh and decompressed: they are in the form of Self-
UnStuffing StuffIt Archives. You do not need to have special software to
perform the decompression.
At Bowdoin we transfer files of this nature from POLAR (a UNIX workstation)
to a Macintosh via TCP/Connect. The settings needed for this transfer are
'Image' and 'MacBinary'. Other users have indicated that "Fetch" also works
nicely. We have, however, heard of problems when using "MacIP"---for that
reason we suggest not using this program when working with our files.
