To EXPORT your system data for use elsewhere, make an Active File (either by reading raw data with a DATA LIST command or by using a GET command to bring in a previously saved SPSS system file), then issue the following:

EXPORT OUTFILE='<UNIX file name>' .

This creates an ASCII file which you can ftp to another system, or write to tape for transport to another location and/or system. To IMPORT a file that has been EXPORTED previously, issue the following (anywhere, even at the very beginning of a session):

IMPORT FILE='<UNIX file name>' .

You will then have an Active File for use during your current session, and you can SAVE it to an SPSS system file or issue analysis commands on it.
