Think laterally.  The computer is logical, so only offers the "IF condition"
or pseudo-random selection.  Maybe you want to browse and pick cases?
Either LIST the variables you might look at, and use $CASENUM as suggested,
or create a new column (call it "pickthis" or anything you like), reorder
the variables so to bring those of interest and pickthis together, then
use the DATA EDITOR view and go through marking the cases you want.  You
will then have your logical condition:
 
   compute pickthis=0.
   EDIT data and mark 1 for selected cases
   if (pickthis=1) ...
