REAGAN'S MESSAGE APPEALS FOR UNITY TO CURB SPENDING
President Reagan appealed tonight to Republicans and Democrats to unite in an effort to control Government spending, saying, ''It's time we reduced the Federal budget and left the family budget alone.'' In his annual State of the Union Message to Congress, Mr. Reagan singled out support of the American family as a major theme of the remainder of his second term. He cited the family as the ''moral core'' of a restoration of the nation's confidence in the future. ''Tonight, we look out on a rising America - firm of heart, united in spirit, powerful in pride and patriotism,'' Mr. Reagan said in a nationally televised speech before a joint session of Congress. ''America is on the move!'' Welfare Study Proposed Although the speech contained few details, Mr. Reagan proposed a study of the nation's welfare system and what he termed the ''web of dependency'' among recipients; ordered a Government review of the possibility of providing insurance for the elderly against ''catastrophic illness,'' and directed the Treasury Secretary, James A. Baker 3d, to determine if the nations of the world should meet to discuss the alignment of their currencies to thwart ''wild currency swings.''
