A CDE Definition
The single quote character (') is sometimes used with double quotes to express quotes within a quoted string. For example, in the dBASE statement ? 'Press the "Enter" key.', the single quotes surround the entire string, allowing the double quotes to be used as actual double quotes. See double quotes.
The double quotes (") symbol is used to delineate a string of text as in the C statement printf ("Press Enter now.\n");. They are also used to delineate a phrase for searching. If you enter "absolute measurement" in a Web search engine, you are asking for an article that contains the two-word phrase, not one that has the two words individually anywhere within the text. See single quotes.
