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

    Most DSR commands can be abbreviated. For example, the
    .AUTOPARAGRAPH command can be abbreviated .AP. To find the
    accepted abbreviations for DSR commands, refer to the format
    section for each command listed under HELP DSR DSR_Commands.

    All DSR commands begin with the Control flag (.) in column 1.
    Multiple commands may appear on one line. The control flag is
    followed by the command text, any arguments to the commands, and,
    if required, the command is terminated with a semicolon (;). For
    example:

       .LEFT MARGIN 10
       .LIST ELEMENT; text
