From a command tool window after changing to the user's mathica
directory with the Unix command cd mathica, enter the command
mathematica to bring up the notebook feature on
Mathematica. A dialog box in the lower left corner of
the screen which reads Mathematica provides startup
information; Initializing text resource manager,
Initializing menus,
and so on. After startup, a pop-up
window labeled ``untitled-1'' will open up. This is a blank
Mathematica notebook in which the user may begin entering
Mathematica commands. One can click on the Help option
to study a wide variety of help options and examples.
After typing any Mathematica command, press
SHIFT-RETURN (hold down the
SHIFT key and press RETURN) to tell
Mathematica to evaluate the input. Users may press
ENTER on the numeric keypad instead of
SHIFT-RETURN. Pressing
RETURN itself gives a new line in the same cell.
Labels such as ln[n]:= and Out[n]= will be added
automatically to the notebook. The first calculation may take longer
than subsequent calculations because the
Mathematica Kernel has to start up. Use the mouse arrow
to position for corrections. To cut or copy entire cells, mark the
corresponding cell bracket with the left mouse button before using the
mouse in making your selection on the Edit options. Concurrently a new
notebook may be opened by selecting New with the left mouse
button on the File option.
The user may open an existing Mathematica notebook
file by positioning the arrow pointer on the File menu to the left top
of the notebook, pressing the left mouse button and dragging it on the
Open.. option. Then the user must specify the directory in which the
file has been previously stored, enter the name of the file, and click
OK. To cut, copy, and paste, choose the corresponding option from the
Edit menu to the right of the File menu. To close the notebook, click
the right mouse button on the gray square with a triangle in it
located at the upper left corner of the notebook, then drag the pointer
down to the Close option. To quit the Mathematica
session, choose the File menu and press the left mouse button and drag
it all the way down to the Quit option. The Quit option from
previously mentioned gray square at the upper left corner will not
completely end the session; if the notebook from which the gray square
was clicked is the only Mathematica notebook currently
in session, it will simply end the notebook and open a new, blank
notebook named ``Untitled-1''.
