ZURICH, Oct 22 - The Swiss franc was a touch firmer against the dollar early in Europe on Monday in range trading, dealers said. The fact that U.S.-led strikes on Afghanistan, which have entered their third week and increased cases of anthrax in the United States, has failed to dent the dollar has increased interest in the unit, they added. Ongoing problems in Switzerland regarding the formation of a new national carrier to replace the collapsed Swissair weighed on the franc's safe haven image. "At the moment there is really no impact from what is going on in Afghanistan or the anthrax cases," a Zurich dealer said. The dollar softened to 1.6410/16 francs, down from 1.6433/39 late on Friday. The franc was expected to trade between 1.6380 and 1.6550 against the dollar for the remainder of the session in the absence of dramatic developments in Afghanistan or fresh terror attacks against the United States or its allies. The euro was at 1.4764/65 francs, a touch firmer from 1.4746/51 late on Friday. The euro was expected to trade between 1.4750 and 1.48 francs, dealers said.
