TOKYO, Nov 11 (Reuters) - Japan's Nikkei stock average was flat on Wednesday as the yen rose, offsetting a surprisingly large jump in domestic machinery orders for September and a forecast for a rise in the fourth quarter.

Tech shares such as Advantest Corp (6857.T: Quote, Profile, Research) slipped after rising the previous day, while nonferrous metals makers such as Dowa Holdings (5714.T: Quote, Profile, Research) came under pressure amid concerns over long-term demand. But Japan Airlines Corp (9205.T: Quote, Profile, Research) rose 4.8 percent after sources said the state-owned Development Bank of Japan will offer a 100 billion yen ($1.1 billion) line of credit to JAL to keep the airline from running out of cash.

The benchmark Nikkei .N225 closed at 9,871.68, up 0.95 point. The broader Topix .TOPX was also flat at 872.29. (Reporting by Elaine Lies)
