What I found useful is creating a variable with all the individual items,
though the number of different patterns in the frequency table may be
awfully large. Seven items may be just right to keep you short of an
unmanageable number of patterns. Syntax:

COMPUTE
pattern=1000000*var1+100000*var2+10000*var3+1000*var4+100*var5+10*var6+var7.

This new variable varies between 0 (no to all items), 1 (yes only to var7),
and so on through 1111111 (yes to all items).
Total possible patterns are 128, though many may not appear in your dataset.
