Sorry, I meant delete from the Before array. This is untested, but should show
the idea.
LONGINT ARRAY FROM SELECTION($tablePtr->;$aBefore)
USE SET($highlightSet)
LONGINT ARRAY FROM SELECTION($tablePtr->;$aAfter)
DELETE SELECTION($tablePtr->)
$size:=Size of array($aBefore)
For ($i;$size;1;-1)
$pos:=Find in array($aBefore{$i};$aAfter)
If ($pos=-1)
DELETE FROM ARRAY($aBefore;$pos)
End if
End for
CREATE SELECTION FROM ARRAY($tablePtr->;$aBefore
