The NCS$RESTORE_CS routine permits the calling program to restore
    the definition of a "saved" collating sequence from a database or
    a file.
    Format
      NCS$RESTORE_CS  cs_id [,length] [,address]
1 – Returns
    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value
    Longword condition value. Most utility routines return a
    condition value in R0. The condition value that this routine
    can return is listed under Condition Value Returned.
2 – Arguments
 cs_id
    OpenVMS usage:identifier
    type:         longword integer (unsigned)
    access:       write only
    mechanism:    by reference
    Address of a longword that NCS uses to identify a collating
    sequence.
    The cs_id argument is required.
 length
    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    Longword that the calling program uses to indicate the length of
    the collating sequence being restored.
 address
    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    Longword that the calling program uses as a pointer to the
    collating sequence being restored.
3 – Description
    The NCS$RESTORE_CS routine, used in conjunction with the
    NCS$SAVE_CS routine, permits the application program to keep a
    local copy of the collating sequence. The NCS$SAVE_CS routine
    obtains the length and location of the collating sequence and
    returns it to the application program. The application program
    subsequently provides this information to the NCS$RESTORE_CS
    routine, which uses it to access the collating sequence.
    This routine also does some integrity checking on the collating
    sequence as it is being processed.
4 – Condition Value Returned
    NCS$_NOT_CS        Name of identifier does not refer to a
                       collating sequence.
5 – Condition Values Signaled
    LBR messages (prefaced by an NCS message) might signal errors
    detected while the process is accessing the NCS library.
