/sys$common/syshlp/helplib.hlb RTL Routines, STR$, STR$ANALYZE_SDESC, Arguments  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 input-descriptor

    OpenVMS usage:char_string
    type:         character string
    access:       read only
    mechanism:    by descriptor

    Input descriptor from which STR$ANALYZE_SDESC extracts the length
    of the data and the address at which the data starts. The input-
    descriptor argument is the address of a descriptor pointing to
    the input data.

 integer-length

    OpenVMS usage:word_unsigned
    type:         word (unsigned)
    access:       write only
    mechanism:    by reference for CALL entry point, by value for JSB
                  entry point

    Length of the data; this length is extracted from the descriptor
    by STR$ANALYZE_SDESC. The integer-length argument is the address
    of an unsigned word integer into which STR$ANALYZE_SDESC writes
    the data length.

 data-address

    OpenVMS usage:address
    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference for CALL entry point, by value for JSB
                  entry point

    Address of the data; this address is extracted from the
    descriptor by STR$ANALYZE_SDESC. The data-address argument is an
    unsigned longword into which STR$ANALYZE_SDESC writes the address
    of the data.
