VMS Help RTL Routines, STR$, STR$TRANSLATE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Translate Matched Characters routine successively compares
    each character in a source string to all characters in a match
    string. If a source character has a match, the destination
    character is taken from the translate string. Otherwise,
    STR$TRANSLATE moves the source character to the destination
    string.
