{\bf Launching Maple}
\bigskip
\noindent
To get into Maple, you will need to follow these directions.
\bigskip
\item{1)}  If your computer is already turned on and the 
Windows desktop is visible, go to step 2 below.  Otherwise,
turn the computer and monitor on, and wait a few minutes while the computer 
``boots up.''  If you do this, eventually you will see a prompt to log 
onto the Novell campus network.  Enter your campus network username and 
password, and go to step 3.
\item{2)}  If your computer is already turned on and the 
Windows desktop is visible, but you have not yet logged on, click the 
Start button.  In the Start menu you will see either
``Log off xxx'', where ``xxx'' is the username of whoever was on 
before, or else just ``Log off...''.  In the first case, it means
that someone else left in the middle of a session.  {\bf YOU DO NOT
WANT TO DO THAT!  IT MEANS THAT YOUR EMAIL, THE CONTENTS OF YOUR
P: DRIVE, ETC. ARE READABLE (AND CAN BE MESSED WITH)
BY WHOEVER SITS DOWN AT THAT COMPUTER NEXT.}  Always log off when
you are finished in a session.  If someone else is logged on, 
log them off.  Then click the Start button again.  Now 
that item in the Start menu should just say ``Log off...''.
If you select that, you will get the Novell login dialog to log on 
yourself.  Enter your username and password.
\item{3)}  You should now see the Windows desktop.  
Double click on Maple V Release 5 shortcut icon.  
\item{4)}  After a few more seconds you should see a new 
Maple V Release 5 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
Worksheets are actually 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.
\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. 
\vfill\eject
\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.) 
  
As we mentioned before, Maple worksheets can contain text
as well as commands and output.  To create a text region you can 
press the $[>$ button above, then the
button marked by a capital T (this changes the region into 
a text region).   Any text can now be entered, and this will
be treated as an ``inert'' comment.  That is, it will appear as
you enter it when you print out the worksheet, and it will
not be treated as Maple input.  After you create a text region,
if you press  the capital sigma ($\Sigma$) 
toolbar button with the cursor placed on that region, you 
can type in a Maple expression in input
format, and have it displayed (in ``inert'' form)
in usual mathematical notation (with 
raised exponents, no asterisks for multiplication, etc.  This is 
sometimes useful for creating ``pretty'' worksheets!

\bigskip
\noindent
{\bf Saving and Reloading your Maple Worksheets}
\bigskip
When you begin working on a
worksheet, you will usually 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.  (You can also save to  a 3 1/2 inch
{\it High Density\/} IBM format diskette.)
Follow these directions:
\medskip
\item{1)} If you are using a diskette, insert it in the diskette drive 
(it's called the a: drive on all the lab machines).  Otherwise 
go directly to step 2.
\item{2)} In Maple, select the SAVE option from the FILE
pull-down menu.
\item{3)} If you are saving your work for the first time, 
you will see a SAVE AS dialog box.  In the Drives box, 
highlight the A: or P: drive as appropriate, then go to the File 
Name box, and type in a name for the file where the worksheet will be 
stored (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 
OK button to write the worksheet to the P: drive or to your diskette.
(You will only need
to type the filename in once in a session.  Subsequent 
saves just update the file.)
\item{4)}  When you have the worksheet saved as you want it,
you can remove the diskette and exit Maple.  
\item{5)}  To update the worksheet further in a later session,
you can read the worksheet back into Maple using the OPEN
option from the FILE Menu.  Get into Maple as above,
(if the worksheet is stored on diskette, insert it in the a: drive), 
and select OPEN from the FILE Menu.  Maple will prompt you as above for the
name of the worksheet with a dialog box very like the SAVE AS
box described above.  Highlight the A: or P: drive as appropriate, then 
the worksheet you want, and click OK.
\bigskip
\noindent
\bigskip
\noindent
{\bf Printing in HA 408}
\bigskip
To print a Maple worksheet in HA 408, you will need to 
log onto the campus network {\it before\/} launching Windows and Maple.
This is done by typing in your network username and password
at the prompts that come up automatically when you boot up.
Then get into Windows and Maple as above.  OPEN the worksheet
you want to print, and press 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 by clicking the Start button and selecting ``Log off.''
