doit is a special menuing
script written by Bruce Foster and named after the famous
Nike slogan, "Do It!" This section assumes that you have
been assigned your own account and know how to log into
hardin, a unix computer running the SPSS
program. You now have access to the Dalton
data on 7,700+ respondents interviewed in the U.S., U.K.,
France,and Germany in 1990-91--which is stored in my master
account. Using the proper "syntax" in
writing SPSS commands under an editing program called
qedit, you can call up variables from these data and
cross-tabulate the variables to learn what factors affect
public opinion and political behavior. Type doit at the unix
prompt[%]: hardin(kjanda)43%
doit You'll be asked to provide a name
for the "syntax" file, which is a text file that contains
data or commands for the SPSS program. You can name this
file what you want, but let's call it
citizen. Name of SPSS syntax
file? citizen The computer will reply by
displaying a screen which begins with the phrase "new file."
get file =
'$CLASS/citizen.sav'. [The
function of this "crosstabs" command will be explained
below.] Type ^k and then x to
leave the editor and return to doit. Immediately on leaving qedit
you'll return to control of doit and see the menu
again: Process the SPSS commands by
choosing option 2: This "End of job" message indicates
that your job ran successfully. To check, choose option 3,
"Display results" from the menu: The computer will then display the output from your spss
run: Press the space bar to see more;
the above is only a partial listing that fits on one
screen. Press the space bar again to see
more; the above is only a partial listing that fits on one
screen. After you reach the end of the
listing, you'll return to the doit menu. If you want to termiinate the job,
choose option 8: Enter your choice:
8 This returns you to the original
unix menu. Type logout and press return. hardin(kjanda) 46% logout
You are finished. Perhaps the better procedure for most of you is simply
to select and copy the SPSS output from your computer
screen and dump it into a word processor. BUT NOTE:
If you copy SPSS output for
entry into a word processor be sure to change the
font to a mono-spaced font, such as Courier, to preserve
the spacing in the tables. If you view the output in a
proportionally spaced font, such as Times, the tables
will almost be unreadable.

Concerning printing SPSS output: The doit print option (4) prints nicely
formatted SPSS output on a laser printer in Room 115 of
the Cresap Laboratory. The output will be labeled with
your netid, but you'll have to sort through other output
to find it. This location may be convenient for some
students, but not for others.
