AUSTRIA DOES NOT INTERVENE TO SUPPORT DOLLAR The Austrian National Bank did not intervene on the foreign exchange markets today to support the dollar, deputy banking department chief Herbert Danzinger told Reuters. He denied a suggestion by a dealer at one Vienna bank that the National Bank had sold marks to support the U.S. Currency. Senior dealers at Creditanstalt and Girozentrale, Austria's two largest banks, said they would have been aware of any National Bank intervention. Any dollar purchases by the Bank today were for purely day-to-day purposes, they said.
