DATA LIST LIST /id1 id2 id3 id4 data1.
BEGIN DATA

2 1 1 1 3
2 2 2 2 4
END DATA.

SORT CASES BY id1 id2 id3 id4.
SAVE OUTFILE='c:\\temp\\database.sav'.

DATA LIST LIST /id1 id2 id3 id4.
BEGIN DATA
1 1 1 1 
2 2 2 2 
END DATA.
LIST.
SORT CASES BY id1 id2 id3 id4.
SAVE OUTFILE='c:\\temp\\delete list.sav'.

***** Start job.
GET FILE='c:\\temp\\delete list.sav'.
COMPUTE del=1.
SAVE OUTFILE='c:\\temp\\delete list.sav'.

GET FILE='c:\\temp\\database.sav'.


MATCH FILES /FILE=*
 /TABLE='C:\\Temp\\delete list.sav'
 /BY id1 id2 id3 id4.

* Next lines deletes unwanted cases.
SELECT IF MISSING(del).
