Installation
                                       
   To install this software, the distribution zip file must be unzipped into
   an appropriate directory on a hard disk drive. Whatever program you
   normally use to unzip ZIP files can be used to unzip the distribution
   file. There are two basic ways of installing this DOS_Prompt version
   of the software.
   
First Method

   The first way is to have all of the executable programs (those whose
   extensions are "EXE" or "BAT") and the ancillary data files (those
   whose extensions are "FLT") in the a directory which is not listed in
   your PATH environment variable. The consequences of this choice are
   that you will need to have this directory be your current directory
   when running the software, and that the data files needed by the
   software have to be in this same directory. The data files are those
   you wish to send, and those you have recorded.
   
   To see the directories listed in your PATH environment variable,
   execute the "PATH" command at the prompt of the DOS_Prompt program
   (i.e. start the DOS_Prompt program and type "PATH", without the quote
   characters, followed by a carriage return).
   
   If you wanted to install the DOS_Prompt version of this software in a
   directory named "HDSSTV" in the root directory of your C: drive, you
   could create that directory with the following DOS_Prompt commands.

  CD C:\
  MKDIR HDSSTV


   Of course this directory could also be created without using the
   DOS_Prompt program. You can choose any name for the directory that
   your system will let you create; the name does not have to be
   "HDSSTV".
   
   Unzipping the distribution file into the directory of your choice
   completes this first method of installation.
   
Second Method

   The second way is to have all of the executable programs (those whose
   extensions are "EXE" or "BAT") in a directory that is listed in your
   PATH environment variable and to modify the included HD-T.BAT file to
   reflect actual directory containing the ancillary data files (those
   whose extensions are "FLT"). Modification of the HD-T.BAT file is
   needed because the DOS_Prompt program does not support the "APPEND"
   command. The consequences of this choice are that any directory can be
   your current directory when running the HDSSTV software.
   
   To see the directories listed in your PATH environment variable,
   execute the "PATH" command at the prompt of the DOS_Prompt program
   (i.e. start the DOS_Prompt program and type "PATH", without the quote
   characters, followed by a carriage return).
   
   Unzipping the distribution file into a directory listed in your PATH
   environment variable will put all of the executable programs and the
   ancillary data files into that directory.
   
   You can also put the HDSSTV software into a new directory that you
   create, and add this new directory to those already stored in your
   PATH environment variable. This accomplishes the same thing as putting
   the HDSSTV software into an existing directory already listed in your
   PATH environment variable.
   
  Modification of the HD-T.BAT file
  
   One line of the supplied HD-T.BAT file needs to be modified in this
   second method installing the software. The original contents of the
   line to be modified are reproduced just below.
   

COPY /B 2TONE-03.FLT /B +CHIRP3B.FLT /B +MOD_OUT.FLT f2w_in.flt



   The modification consists of adding parent directory information to
   the 2TONE-03.FLT and CHIRP3B.FLT file specifications, resulting in
   absolute path names for these two files. If you put these two files in
   a sub-directory called HDSSTV in the root directory of your C: drive,
   then the line in the HD-T.BAT file should be changed to the one listed
   just below.
   

COPY /B C:\HDSSTV\2TONE-03.FLT /B +C:\HDSSTV\CHIRP3B.FLT /B +MOD_OUT.FLT f2w_in.flt



   You don't have to use a sub-directory named HDSSTV in the root
   directory of your C: drive. You just have to have the correct (for
   where you put them) absolute path names for the 2TONE-03.FLT and
   CHIRP3B.FLT files in the line of the HD-T.BAT file that refers to
   them.
   
Testing the Installation

   From the directory containing the supplied DEMO.BAT script, execute
   this script as a DOS_Prompt command. When this script finishes, check
   that the files "MODE_DEF.H" and "B2S_IN.SAV" are the same.
