The vbscript code that I posted does that. To set a fixed pitch font, 
change <body> tag to <body STYLE=""font:10 pt courier"">

If desired. you can easily code it to receive input through stdin, but 
that usually implies user operation from the command line.

Rather easy.  Essentially, the HTA has a button and a textarea.  The
existing JScript for WSH is modified so that the code is just
declarations of globals and functions, followed by a call of the main
function :-

       if (typeof window == "undefined") SEAKFYLE()

In CScript, that call calls, and all still works as before; in HTA,
that call does not call, but the button does it instead.

The HTA "include"s SEAKFYLE.JS, and also contains script

       Fawm = document.forms[0]

SEAKFYLE.JS uses the value of Fawm to write to the textarea, and the
truth of Fawm for minor code changes, such as reading the command line
from an "<input type=text" in the HTA.

Query : is there an easy way to resize the textarea vertically when
the HTA window is resized, so that the form comes within a gnat's
whisker (0.5 ex, or a few px) of the bottom of the window, and if so
what is it?

Note that HTML Applications can take command like arguments as well by
using windows.dialogArguments

More info should be here:
<http://msdn.microsoft.com/en-us/library/ms536496%28v=vs.85%29.aspx>

The WScript object is not available in an HTA. Alternative methods
must be used.

Why do you want/need a *.BAT file? If *.js is registered to open with
Cscript.exe or Wscript.exe, then it would be sufficient to simply type
SEAKFYLE.JS at the command prompt. Passing arguments to the script can
be managed by the WScript.Arguments collection:

That's well worth knowing.  I could use that to pre-load the input line;
and I can add an option, command-line only, to auto-start after pre-
load. ... Except that neither windows nor window.dialogArguments appears
to exist. ... Needs   <hta:application ID="oHTA"  and then
alert(oHTA.commandLine) shows the command line.

I think that, in HTA mode, no path of execution should now lead to a
WScript.  Because of the heritage of the "design" of the code, detected
errors lead to a chain of function calls used as GOTOs, since they ended
up in the original Pascal with a Halt(N) call.  In WSH, WScript.Quit(N)
does the same.  I'd like to use something similar in HTA mode; but the
only way of stopping that I know is to exit all routines and fall off
the end of the script, which would be tiresome to arrange.

That problem is now  circumvented.

I prefer to change such defaults as little as possible.  I'd have to
remember to do it on other machines, and other users would also need to
do it.  There could be other *.js files needing to run in WScript.  But
I've added the possibility to the description.

I'm using WScript.Arguments already.

It is rather too much changed from a version that I no longer have to
import, or to be easy to follow.

Having seen it working, aesthetics demand that the textarea is sized to
fill the rest of the form, and the form is sized to only nearly reach
the bottom of the viewport.  But   @FrmMain  margin-bottom: 5px;  does
that.

Resizing then is nice, or will be once I've trapped the error that
occurs when the bottom is dragged up too far.  This does it :
TA.style.height = Math.max(0, TA.parentNode.offsetHeight - 10) + "px";

The <H3> wastes height !!  I'll stick with <big> or equivalent.

The ROWS control seems not to work; but it has no useful function with
auto-resizing.  Removed.

The SEEK button failed, because of its re-naming, fixed.

I was somewhat surprised that   Fawm = document.forms[0];   in the HEAD
works when the actual form is in the body.

There is at present one remaining infelicity: the heading (and other)
text, when wrapped because of Zoom or narrowing the window, wraps under
the following element.  That's now mitigated by shortening the heading
line.

If IE gets Zoom Text Only, I suppose the vertical sizing will have to be
redone in ex or em units.

Indeed, I was staring at the wrong msdn page (not to mention the

Since I was correct only in recalling the idea and not the API, it
would be nice if seakfyle.js didn't perpetuate my bad advice at the
bottom. A generic attribution or nothing at all would be fine with me.

Removed, some while ago now!

You'll probably have noticed how I am, for the time being, indicating
what I've changed in your HTA; for example, auto-start is available
from the SEEK.HTA command line, and the layout is tighter.  Also,
SEEK.BAT is no longer limited to 8 Options.

Instead of using WScript.Quit at the end of performing a non-
continuable Option, I now set a Boolean to indicate that the option is
wanted.  The Boolean can then be tested in the main routine; if set,
the Option routine is called and returns, and from there it is easy to
in effect GOTO near the end of the main routine.

SEAKFYLE.HTM has a list of what that I use in CScript mode I have not
yet been able to do in HTA mode.

For some inscrutable reason, my newsreader seems to think that this
thread, or the pair of us, is kill-ruled.  Unless I recall the
possibility at the right time, that delays getting the item as a News
article to where I like to reply from.  Therefore, see sig.

Thanks for your continued help.

When Windows and programs are installed files types are created. Some
applications hijacks extensions. They keep it meaningful or give it all
a same name. The logic is still the same - what Mayayana has stated. If
it is in the registry, it is a known file type. Otherwise, it is
unknown.

Your question was malformed. It did not request to provide code to 
demonstrate a different method from the one you previously chose. As 
indicated, your answer can be found in HKCR but effort on your part is 
necessary to capture it.
