if [ $? -ne 0 ] ; then no_result ; fi
activity="create head"
if [ $? -ne 0 ] ; then no_result ; fi
activity="create head"
-grep -v '^\ *$' $TEMPDIR/pspp.list | head -2 > $TEMPDIR/head
+grep -v '^[ \r]*$' $TEMPDIR/pspp.list | head -2 > $TEMPDIR/head
if [ $? -ne 0 ] ; then no_result ; fi
activity="extract data"
if [ $? -ne 0 ] ; then no_result ; fi
