       /DOLLARS[=string]

    Sets the EOF indicator to the specified string of 1 to 15
    characters. Specify a string if the input data contains one
    or more records beginning with the string $EOD. Enclose the
    string in quotation marks (" ")  if it contains literal lowercase
    letters, multiple blanks, or tabs. If you do not specify /DOLLARS
    or if you specify /DOLLARS without specifying a string, you must
    use the EOD command to signal the end-of-file (EOF).
