{\bf Launching Maple}
\bigskip
\noindent
To get into Maple, you will need to follow this process.
\bigskip
\item{1)}  When you start a session,
you should see a Novell Client window with prompts for your username
and password for the campus
network.  (If the Windows desktop is showing, that means
previous user has probably not logged off.  Use START/Shut Down/Log
Off Holy Cross to terminate their session and start afresh.)  Enter your
username (full context) and password.
\item{2)}  You should now see the Windows desktop.  
Double click on Maple 8 shortcut icon.  
\item{3)}  After a few more seconds you should see a new 
Maple 8 window, with a ``subwindow'' marked
Untitled (1) opened inside it.  The Untitled (1) window is a 
blank {\it Maple worksheet\/}.  

\bigskip
\noindent
{\bf Maple Worksheets}
\bigskip
\noindent
Worksheets are integrated documents where any or all of the following can 
be done: 
\medskip
\itemitem{a)} you can type in commands from the keyboard 
at the {\it input prompts\/} $[>$, to ask Maple to perform
many different kinds of calculations, 
\itemitem{b)} Maple will generate output (numerical values,
symbolic formulas, and graphics), 
\itemitem{c)} you can modify commands, generating new output,
in our session today.    
\itemitem{d)} you can enter text to annotate and explain the 
results of computations.
\medskip
\noindent
Take a few seconds and notice the 
features of this window -- especially
the ``tool bar'' across the top with the icons for various operations, 
the ``scroll bar'' on the right that you can use to move around 
within the worksheet, to see previous input and output lines, etc. 
\bigskip
\noindent
{\bf Input and Text Regions in a Worksheet\/}
\bigskip
A new input prompt will be generated automatically at the 
bottom of a worksheet each time you enter a command and
execute it at the end of a worksheet in progress.  
You can also {\it insert a command prompt\/}
and an input region at any point in the worksheet by  
placing the cursor at the desired location and
pressing the toolbar button marked with $[>$.  (After executing
an inserted command like this, Maple will drop to the 
next input line, so to insert several input lines in the
middle of a worksheet, you will need repeat the above.) 
  
Maple worksheets can contain text
as well as commands and output.  To create a text region, 
press the $[>$ button above, then the
button marked by a capital T (this changes the region into 
a text region).   Text can now be entered, and that will
be treated as an ``inert'' comment.  That is, it will appear as
you enter it when you print out the worksheet, but it will
not be treated as Maple input.  Within a text region,
if you press ($\Sigma$) 
toolbar button with the cursor placed on that region, you 
can type in a Maple expression in input
format, and have it displayed in usual mathematical notation (with 
raised exponents, no asterisks for multiplication, etc.)  This is 
sometimes useful for creating worksheets with explanations
or comments on the work you have done if you want to include a formula.  

\bigskip
\noindent
{\bf Saving and Reloading your Maple Worksheets}
\bigskip
When you begin working on a
worksheet, you will want to {\it save your work\/} every
once in a while in case a computer problem develops, or in case
you need more than one lab session to complete the work you are
doing.  This can be done most directly by saving to your network P:
drive.  Follow these directions:
\medskip
\item{1)} In Maple, select the SAVE option from the FILE
pull-down menu or press the toolbar icon that looks like a diskette.
\item{3)} If you are saving your work for the first time, 
you will see a SAVE AS dialog box.  Make sure your campus network
P: drive is showing in the {\it Save in:} box, then go to the {\it File 
name:} box, and type in a name for the file (any string of letters 
and digits -- no spaces -- no more than 8 characters long is OK) 
type in a period after the file name you chose and then the 
``extension'' {\it mws\/} for Maple work sheet.  
For instance, a good choice might 
be something like {\it labday1.mws\/}.  Then click the 
Save button.  You only need
to type in the filename in once in a session.  Subsequent saves 
(i.e. FILE/SAVE or clicking the diskette toolbar icon) just update the file.
\item{4)}  When you have the worksheet saved as you want it,
you exit Maple, or continue working.  
\item{5)}  To update the worksheet further in a later session,
get back into Maple as above, and
read the worksheet back into Maple using the OPEN
option from the FILE Menu or the ``opening folder'' toolbar button.  
 Maple will prompt you as above for the
name of the worksheet with a dialog box very like the SAVE AS
box described above.  Make sure your campus network P: drive is
showing in the {\it Look in:} box, then highlight
the worksheet you want, and click the Open button.
\bigskip
\noindent
\bigskip
\noindent
{\bf Printing in HA 408}
\bigskip
To print a Maple worksheet in HA 408, click the toolbar icon that looks
like a printer, and press OK on the PRINT dialog box (the settings
should be set up correctly to print automatically).  Your 
output should appear shortly on the printer at the end of the lab. 
If you have problems, or if the printer runs out of paper, come and 
get me or another math faculty member for help.
(If several print jobs are sent at the same time, you may need 
to wait a short time.)
\bigskip\noindent
{\bf Getting Out}
\bigskip
When you leave, quit the Maple window (FILE/EXIT), and log off the 
campus network (START/Shut Down/Log off Holy Cross).
