   What is an Environment Editor???
    An Environment Editor is a full screen editor for modifying your
    DOS environment without batch files and loads of typing. It also
    allows you to have longer variables (350 characters) than
    DOS allows, to save different Environments to disk and also to load
    them back into memory at will. Used in your autoexec, it allows
    you to define long paths at bootup and also allows you to choose
    between saved environments.
    The Maximum number of lines is 250. (350 x 250 = 87500) Way Larger
    Than Your Environment could EVER BE!!!
    (DOS limit on Environment size is 32K)

    A word about long Environment strings.
      If your Path or any other Environment variable exceeds 127
      characters in length and you type PATH or SET to display them,
      DOS will only show the first 127 characters. Don't get worried,
      this is an artificial limit imposed by DOS, the PATH and all other
      environment strings are still there.
      If you're skeptical, put a directory in your path past 127
      characters and then run a program in that directory.

  What An Environment Editor isn't.
    It won't change the size of your environment specified in your
    config.sys.
    It won't repair the hole in the Ozone Layer or plant more trees
    either. (But you can)

  History of EV.
    In January of this year I was working on some C, ASM, and Clipper
    code and kept having to change my environment to accommodate 3
    different compilers. So in a flash of inspiration I decided to
    write an Environment Editor.

    After tracking down the last "Node to Nowhere" towards the end of
    the month, a usable product emerged. Now I find that I use it every
    day.  I hope You will too.

  Registration:

    Please, if you find this program useful a nominal registration fee
    of $15.00 is required if you want support, upgrades and other
    utilities as I write them.

    Below is a list of parameters and active keys.
    Enjoy!



  Environment Variable:
    EVPATH=
      Determines where all Environment files are placed and retrieved
      from. Usually your local drive when on a network.
      If not set, default is current directory.
      ex. EVPATH=C:\EV\    (trailing backslash required)


  Command line:
    Command line usage is as follows. All parameters are optional.
    EV [file]
      Loads file directly into DOS environment and exits.
      If no extension is supplied, ".ENV" is assumed.

    EV /l
      Displays a pickbox of Environment files in the current
      directory. ENTER selects a file and loads it into the DOS
      environment and exits. ESCAPE exits without loading file.

    EV /d
      Displays a pickbox of Environment files in the current
      directory. ENTER selects a file and loads it into the Editor.
      ESCAPE exits without loading file.

    EV (No parameters)
      Starts editor and loads current DOS environment for editing.


  Editor:
    F1         Help Screen.
    F10        Writes editor contents to DOS Environment and exits.
    F5         Reloads current Environment into editor.
    F6         Prompts for filename and saves contents of editor for
               reloading later. Don't put an extension on the file.
               The file will have an extension of .ENV regardless of what
               you type!
    F7         Same as the /d command line switch.
    HOME       Moves cursor to the beginning of the current line.
    END        Moves cursor to the end of the current line.
    ARROW KEYS Move cursor around editing buffer.
    PAGE UP    The Usual PAGE UP Thing.
    PAGE DOWN  The Usual PAGE DOWN Thing.  (enough said)

    ALT-D      Deletes a line.
    CTRL-Y     Same as ALT-D.
    ESCAPE     Exits editor.




  Environment Files
    Environment Files are a representation of all your
    Environment Variables saved to a file. These Files can be loaded
    directly into memory by typing EV <filename>.
    If the amount of memory required to load the file is more than is
    allocated by command.com, an error message will display. You can
    still load the file into the editor to change it (make it smaller).

    My apologies to those who have an earlier version of EV, I had to
    change the file structure. There is a utility in this zip file to
    convert the old Environment Files to the new format.
    You can continue to create Environment Files with a text editor but
    they must be converted before use!

    The syntax for the conversion program is:
      ASC2ENV <Ascii File Name> [environment file name]

      the first parameter is required. If you only pass one file name,
      it will be overwritten.

      The OPTIONAL second parameter is for a filename if you want to
      preserve the original file.

      In order for the Environment Files to show up in the file pick
      list, they must have an extension of .ENV . Files created from
      within the editor will automatically be supplied with this
      extension. Files being loaded DIRECTLY into memory can have any
      extension you wish, but to keep things simple, an extension of
      .ENV is strongly suggested.
