NAME
     csdupdat -	create/update a	CSD ASER database from ascii FSER
     files.

SYNOPSIS
     csdupdat	[   -if	  ]	 input_fser_file   [   -of   ]
     output_database_file [ -ansi ]

DESCRIPTION
     csdupdat reads an ascii FSER file and create  or  updates	a
     Cambridge Structural Database ASER	file suitable for search-
     ing  by  Quest  and  Vista.  csdupdat  exits  gracefully  on
     Control-C	interrupts,  finishing any outstanding i/o on the
     current ASER entry.   REFCODEs  from  the	input  FSER  file
     overwrite	any  equivalent	REFCODEs that occur in the output
     ASER file.	Otherwise csdupdat is a	merge operation.

OPTIONS
     -if input_fser
	  The file from	which FSER entries are to  be  read.   If
	  not specified	then csdupdat reads from standard input.

     -of output_database
	  The name of the database to  merge  the  FSER	 records.
	  This	need  not  be  a  new file although existing ASER
	  entries with the  same  REFCODE  will	 be  overwritten.
	  This file must be specified on the command line.

     -ansi
	  print	the output in a	groovy manner for ansi terminals.

ENVIRONMENT
     csdupdat recognises the environment  variables  CSDHOME  and
     CSDMACHINE.

     CSD_DB_REORDER_BYTES
	  Interpret input CSD databases	with an	integer	byteorder
	  specified by this environment	variable.

BUGS
     csdupat will take REFCODEs	in any	lexical	 order	and  sort
     them  into	alphabetical order for output.	However	for effi-
     ciency reasons it is best that the	refcodes are presented in
     alphabetical order.
