To strengthen its European business, Powersoft Corp expects to acquire two of its distributors here in the near future: it will continue introducing products this year in languages including Italian, French, German and Korean, it said at the Hambrecht & Quist technology conference; addressing rumours that its margins are eroding as a result of pricing pressures in the client-server market, it said margins are holding up, and responding to another rumour that customer Dun & Bradstreet Corp was unhappy, it said it is a happy customer and an important client; the firm’s tools product update, PowerBuilder 4.0, will be available this year under the Windows, Unix, Macintosh and Windows NT environments.
