Description

   If this is the first call to LBR$PUT_RECORD, this routine first
   writes a module header and returns its RFA to the 2-longword
   array pointed to by txtrfa. LBR$PUT_RECORD then writes the
   supplied data record to the library. On subsequent calls to
   LBR$PUT_RECORD, this routine writes the data record beginning
   at the next free location in the library (after the previous
   record). The last record written for the module should be
   followed by a call to LBR$PUT_END.
