The BOX-JENKINS procedure was dropped from SPSS-X at version 3.0, some
time in the late 1980s. SPSS has a TRENDS module with a variety of time
series procedures, including ARIMA. To see if your site has the TRENDS
module installed, you can talk with the person there responbible for
SPSS, or just try running the command ARIMA with nothing else there. If
you get a message about the command not being defined, then you don't
have it. If your message complains about no variables or something like
that, then you do have it.
