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 the ordinary mail, send 
such a request to me.  

Currently Releases 4 and 5 of the labs has been placed in the ftp files. 
Detailed descriptions of the contents of each release will be found in the 
files README-Rel-4-ftp and README-Rel-5-ftp.  Release 5 contains the
newest versions of the laboratory notebooks (as of mid-June), all fully
compatible with Mathematica v2.0---in particular, most of these notebooks 
will not run under v1.2.  For this reason, Release 4 has been retained as a 
convenience for those who are still using Mathematica v1.2. 

By the end of the summer we intend to post Release 6, which will contain 
revised versions of the laboratories.  The revisions to the first and 
second semester labs will be relatively modest; the bulk of revision work 
will be with the third semester labs.

We also intend to post important revisions as they are completed (i.e., 
prior to Release 6) in the area pub/calculus/revisions.  Those of you 
interested in having the most current versions of our labs should check 
this area regularly.  In particular, we have just added the file 
SpecialItems.sit to the revisions area.  This was accidentally left out of 
our original configuration of Release 5.  A short description of the file 
will be found in the text document rel5correction.txt.

If you wish to receive information from us on a regular basis, please send 
a request asking to be placed in our "Dissemination Network." 

What follows is a sample ftp session along with some explanatory comments;
this should enable you to obtain any file currently in our ftp directory.

(I wish to thank my colleague Steve Fisk for designing and setting up
this ftp directory.)

NOTE:  The workstation 'POLAR' on which the ftp files 
are found has been experiencing a lot of problems this summer.  
If you have difficulties connecting to POLAR, or if the ftp 
commands do not seem to be yielding the desired results, disconnect and try 
again later.  Hopefully these problems will be solved shortly.


Logon to a computer with Internet access and enter


You will be answered by the following statements:

     Connected to                         
     220 FTP server: ready.

Now login with the username 'anonymous' and 
your e-mail address as the password.
     Name ( anonymous      
     331 Guest login ok, send ident as password.
     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-4, release-5, or revisions.

     ftp> cd pub/calculus/release-4
     200 PORT command successful.

You now can ask for a list of what is in the directory

     ftp> dir 
     200 PORT command successful.

     226 Transfer complete.
     210 bytes received in 0.17 seconds (1.2 Kbytes/s)

To transfer an individual file use the following command:

     ftp> get README-Rel-4-ftp      

To transfer all the contents of the current directory use the commands

     ftp> mget *
     mget README-Rel-4-ftp? yes (you will be asked about each file)

To change to one of the other directories use the command

     ftp> cd ../release-5

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.
