 == READ-ME.TXT

 Welcome  to the Saguaro Astronomy Club Double Star Database.  This  file  will 
 give you some info on what is in each of the files included on these disks.  

 == FILES:

 There  are two 360k diskettes in this SAC Double Star database release,  which 
 contain 10 files, but some are duplicated.  They are as follows:

 Disk_one:
 READ-ME.TXT = this brief overview file
 SAC-DBL.DOC = the documentation for the database
 INSTALL.BAT = an program to install the files on a hard disk
 PKUNZIP.EXE = a utility to unZIP the other files
 DBL20A.ZIP  = the database from 00 hr to 05 hr 59.9 min
 DBL20B.ZIP  = the database from 06 hr to 10 hr 59.9 min
 DBL20C.ZIP  = the database from 11 hr to 16 hr 59.9 min

 Disk_two:
 INSTALL.BAT = a second copy of the hard disk install program.
 PKUNZIP.EXE = a second copy of the unZIP utility
 READ-ME.TXT = a second copy of this file.
 DBL20D.ZIP  = the database from 17 hr to 19 hr 59.9 min
 DBL20E.ZIP  = the database from 20 hr to 23 hr 59.9 min
 SACDBL.ZIP  = a report generator program with it's own documentation
 TONIT.EXE   = an outstanding general astronomy utility program
 
 The  DBL20A.ZIP  thru DBL20E.ZIP files will each unZIP into  individual  ASCII 
 text  files,  with datafields separated by commas and  delimited  with  double 
 quotes.   The SACDBL.ZIP file will unZIP into eight separate files which  make 
 up a public domain report generator program customized for this database.  All 
 of the ZIPped files were created with PKZIP release 110.  PKUNZIP is  provided 
 with  the permission of PKWare, Inc.   TONIT.EXE is provide courtesy of  Lenny 
 Abbey and Abbey Information Systems.


 == HARD DISK USERS:

 The INSTALL.BAT program will unZIP the files onto your hard disk.  It DOES NOT 
 create  a  subdirectory.  BEFORE YOU INSTALL THE PROGRAM,   YOU  SHOULD  FIRST 
 CREATE  A SUBDIRECTORY TO HOLD THESE FILES.  As an example, you can  create  a 
 subdirectory  called SACDBL on your C drive by entering the following  command 
 at the C:> prompt:

                           MKDIR C:\SACDBL 

 Now,  with  the  subdirectory created, you can use  the  INSTALL.BAT  program.  
 Place distribution disk one in the A: drive, and enter the next two lines:
 
                          A:   
                          INSTALL A: C:\SACDBL     

 (You can substitute other drive letters, if needed.)  The program will  prompt 
 you from that point.

 == FLOPPY DISK USERS:


 The  INSTALL.BAT  program  will work to unZIP  the  datafiles  onto  floppies.  
 However, if you are using 360k floppies, you will need to put each of the four 
 files on a separate diskette.  When the INSTALL.BAT program has extracted  the 
 data  files  and moves on to the SACDBL program, it will also extract  onto  a 
 360k  diskette,  but  it will not operate on a 360k drive.  You  need  a  high 
 density drive to use SACDBL with floppies.


 == CREATING REPORTS:

 See  the  SAC-DBL.DOC  file  for the layout of  the  database.   Nearly  every 
 database manager on the market is able to read data in this format.

 We have included a public domain database report generator.  SACDBL.ZIP  has a 
 separate documentation file called REPORTS.DOC, plus seven other files related 
 to the report generator program.

 == OTHER DETAILS:

 The  SAC-DBL.DOC  contains the key to the many abbreviations used  within  the 
 database.   Please take the time to look through the documentation.   When  we 
 put the SAC deep sky database together, we got lots of calls and letters  from 
 people with problems that were addressed in the documentation!


 If  you  are going to use your own database manager program with  this  double 
 star  database,  you may want to merge the five separate  datafiles  into  one 
 large file.  The five DBL20?.txt files can be combined into one large file  by 
 using the DOS copy command.  The command is:

 COPY DBL20A.TXT+DBL20B.TXT+DBL20C.TXT+DBL20D.TXT+DBL20E.TXT DBL20.TXT

  This will append the five files into the one file called DBL20.TXT.  However, 
 you will NOT want to do this if you are going to use the SACDBL program as  it 
 will take care of this during the initial installation of the program.

 Good luck, and let us know if you see anything good!
