Library /sys$common/syshlp/pca$help.hlb SEARCH, Qualifiers, /IDENTIFIER  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Names the string as an identifier. The specified range is
    searched for the first occurrence of this identifier. If the
    string (identifier) is bound on either side by a character that
    can be part of an identifier defined by the SET LANGUAGE command,
    then it is not displayed. The search continues until it finds an
    occurrence of the string that is not bound by such characters.
