Ok, I changed my statement to

select towns.fullname, towns.Town , towns.ccode, 'Current' as SortOrder ;
			from towns ;
			where towns.Town = BldMstr.Town ;
			union ;
			select towns.fullname, PostRegn.joiningtwn as Town, towns.ccode, ;
			'New   ' as SortOrder ;
			from PostRegn, towns ;
			where PostRegn.joiningtwn = towns.Town and PostRegn.Town = BldMstr.Town ;
			order by 4 ;
			into cursor tRegion

and it solved the problem.
