VMS Help SET, SYMBOL, Qualifiers, /VERB  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies that the values of the /SCOPE qualifier pertain
    to the translation of the first token on a command line as a
    symbol before processing only. It does not affect general symbol
    substitution.

                                   NOTE

       Caution must be used if the SET SYMBOL/VERB/SCOPE command
       is used more than once in a command procedure. Because
       DCL uses the translation behavior when looking for a
       label or subroutine, execution may be different running
       in one mode than in another. Compaq recommends that the
       SET SYMBOL/VERB/SCOPE command be used once as part of
       the command procedure setup and left in that mode for the
       duration of the procedure.

    The /VERB qualifier is incompatible with the /ALL or the /GENERAL
    qualifier.
