Debt Disclosure [Abstract]
Debt Disclosure	LONG-TERM DEBT AND CREDIT AGREEMENT: We had no long-term or short-term debt outstanding as of January 29, 2011 or January 28, 2012. During the past several years and through the first quarter of fiscal year 2010, we maintained a $100 million credit facility with a maturity date of April 30, 2010. Based on our then current cash and short-term investment positions, and projected cash needs and market conditions, we elected not to negotiate a renewal or replacement of the credit facility. As a result, the credit facility expired on April 30, 2010 in accordance with its terms.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
