    EditVar/EditV32/EditV64 and Choose/Choose32/Choose64 v2.0

    Home page:

    EditVar/EditV32/Editv64 and Choose/Choose32/Choose64 are command-line
    tools designed to allow for user input in shell scripts (AKA batch
    files). There are three .exe files for each program: DOS, Win32, and Win64.

    EditVar works by obtaining the contents of an environment variable and
    presenting it for interactive editing. If you make any changes to the
    variable's contents and press Enter, EditVar writes the changed variable
    to the parent environment of the program that started it (typically
    Cmd.exe). EditV32 requires Windows NT 4.0 or later; for Windows 9x/Me,
    use the MS-DOS version.

    EditVar is similar to the Cmd.exe Set /p command in Windows 2000 and
    later, but it may be preferable for the following reasons:

    * It allows you to edit a variable, not just set one.
    * It can limit the length of the typed variable.
    * It can mask the typed input for simple password security.
    * It can limit typed input to numbers only.
    * It offers a timeout feature (useful when a script needs to run
    * It can automatically "escape" reserved shell characters in variables
    it creates.
    * It provides useful exit codes: For example, an exit code of 4 means
    that the user pressed Ctrl-C to abort.
    * It comes with an MS-DOS version that works in Windows 9x/Me as well as
    on MS-DOS boot media.

    Choose is similar to the Microsoft Choice tool, but it has more
    features. Here are some reasons why it might be preferable to Choice:

    * It doesn't beep when the user makes an invalid choice.
    * It offers a "default key" feature, which lets a user press Enter to
    select a default choice.
    * It comes with a DOS version (useful for MS-DOS boot media).
    * The Win32 version's timeout feature doesn't get confused when you run
    multiple instances in separate console windows (this was a problem with
    earlier Win32 console versions of Microsoft's Choice tool).
    * It can suppress the display of the user's choice.
    * It offers a "line input" mode where the user must press Enter after
    making a choice.

    What's new?

    Version 2.0 includes 64-bit Windows versions.

    I ran across a DOS-only *.com utility somewhere long ago (in the pre-NT era)
    that accepted input into an environment variable whose name was hardcoded. I
    adapted it to accept a variable name parameter:

    CIAO varname=prompt

    and included a few other optional features like masking the input as typed
    and outputting arbitrary string with CRLF suppression. Bing written in
    assembler it was tiny (about 1K IIRC). I used it lots and finally toasted it
    when I found I was no longer working in DOS. Shortly thereafter I kicked
    myself as a practical application presented itself in our environment!
    Workaround was to open a text file in a tiny .com text editor, but it was
    way uuuugly. So ugly I gave up on it, so now I'll try it with Bill's
    utility. Way to go.

    I believe that the [NT] utility NIRCMD.exe available from:

    ....can do what you described (the use of 'masked' input in a dialogue set up
    to set an environment variable).

    Hi Tim, I pulled up the 'nircmd' web page, and I didn't see where it can
    create a password-input dialog...? (I may have missed it; I didn't look
    that hard...)

    In any case, a password-input dialog box is not the same as reading from
    console input, like EditV32/EditV32 does (as does the ScriptPW.Password
    COM object, which mysteriously disappeared from Windows Vista).

    In my (admittedly biased) opinion, EditV32/EditV64 is better than the
    ScriptPW.Password COM object because it has more features.

    You're welcome.

    I tried using your utility, and am happy to say that it was a complete
    success. In fact, it is superior to my now lost CIAO.COM utility in its

    [where's that dang disable built-in trackpad switch!]

    I tried using your utility, and am happy to say that it was a complete
    success. In fact, its editing facility made it much more useful in my
    application than my much simpler input routine.

    That is gratifying to hear. Thanks for posting.
