The dollar index ended little changed on Friday as it stayed on track for a record eighth month of gains on improving U.S. data and comments from Federal Reserve officials that bolstered bets for a interest rate rise later this year.
This measure of the greenback against the euro, yen and four other currencies was set to mark its longest streak of monthly gains since the greenback was floated as a fiat currency in 1971. February's gain of about 0.52 percent, however, was the smallest of the eight months.
The dollar overcame earlier month-end selling that followed a rally on Thursday, as more evidence suggested the U.S. economy will expand in the coming months.
"The trend is still in place to support the dollar," said Eric Viloria, currency strategist at Wells Fargo Securities in New York.

The dollar index initially eased from a one-month high set on Thursday, before ending the day flat at 95.295.
The greenback hovered near a one-month peak versus the euro, last up 0.08 percent at $1.1188. It firmed 0.24 percent against the yen at 119.700 yen.
The government said on Friday it downgraded fourth-quarter U.S. gross domestic product growth to a 2.2 percent annual pace from an initial estimate of 2.6 percent. Economists polled by Reuters forecast a revision down to 2.1 percent.
