NEW YORK, AUG. 31 -- The dollar closed slightly higher today in quiet trading, supported by end-of-the month positioning by traders. Gold closed lower.

"We came in this morning with bearish sentiments," said Henry Weiland of NatWest U.S.A. "But when you have New York or London closed, it's going to be quiet." Markets in London were closed today for a bank holiday.

Against the West German mark, the dollar ended at 1.8160, up from Friday's 1.8120. Earlier in Frankfurt, the dollar fell to 1.8152, down from 1.8204 Friday.

The dollar rose to 142.50 yen, up from Friday's close of 141.90. Overnight in Tokyo, the dollar rose to 142.35, up 0.85 yen from the previous 141.50.

Dealers in Tokyo said there was evidence of minor intervention in support of the dollar by the Bank of Japan.

Weiland said that while the overall market sentiment for the dollar remains bearish, the week ahead should be quiet.

He said the market might respond to the July report on the index of leading economic indicators, scheduled for release Tuesday.

"The expectation is an increase of 0.7 percent," Weiland said, "and if it's higher, the dollar may move a tick higher."

In New York, the pound fell slightly to $1.6310, down from $1.6336 Friday.

The dollar slipped to $1.3192 Canadian from $1.3196.
