VMS Help DSR, DSR Flags, Substitute  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Subsitute flag ($$) is the only flag that must be used in
    pairs. When the flag is turned on, it causes either a date or
    a time to be output. The output is determined by the word you
    associate with the flag pair; for example, $$Date. See the output
    in the following example.

    When the Substitute flag is turned on, any dollar sign character
    ($), even if it is not paired, must be preceded by an Accept flag
    if it is to be taken as normal text by DSR.

1 - Default

    Recognition is turned off. To turn on recognition, you must use
    the .FLAGS SUBSTITUTE command.

2 - Examples

    The following table shows the use of the substitute flag. The
    output file will contain the date and time that DSR processing of
    the file began.
