library_index

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   Library control index returned by the LBR$INI_CONTROL routine.
   The library_index argument is the address of the longword that
   contains the index.
 

retary

   OpenVMS usage:vector_longword_unsigned
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference
   Array of 128 longwords that receives the library header. The
