NAME
       quasar - program for extracting data from a STAR formatted file

SYNOPSIS
       quasar < request-file-name

DESCRIPTION
       Quasar  is  a fortran program for extracting data from a STAR formatted
       file.  It is intended to demonstrate a general approach to processing a
       STAR file.

       Quasar reads a list of data names (from the standard input device 5) to
       be extracted from the STAR archive file. This is  referred  to  as  the
       "request"  list  or file. This file also contains the names of the data
       blocks to be searched, and the names of the  archive  and  output  file
       (these  are  specified  as  extensions  to  "star_arc_" and "star_out_"
       respectively).  If the archive and output files are not specified  they
       are assumed to have the filenames "STARIN" and "STAROT". Requested data
       items are output in the order requested. The  same  data  item  may  be
       requested  up to five times.  The archive file can be checked for logi-
       cal integrity by entering the string "star_log" into the request  list.
       No data items will be output in this case.

       Quasar  allows  for  "wild  card"  requests for data names. A data name
       request containing a trailing underline is a request for all data names
       matching  the  string preceding the underline. The request for "_" will
       return all data items in the specified data block. Data names are  case
       insensitive.
