Strings contain groups of alphanumeric characters which are treated as a unit of data by the SCPI parser. You may delimit embedded strings with either single (') or double (") quotation marks. Strings are case-sensitive, and spaces act as legal characters just like any other character. For example, this command saves a setup file:

    :DISK:SETup:SAVE "Test4Setup.seti"
