1. Date attribute of a file
Is there any way with Euphoria that I can write read a file, modify it,
and write it back *without* changing the date?

You'll have to save the "time stamp" of the concerning file before writing to
it, and at the end that time stamp must be restored.
This can't be done with built-in Euphoria routines, but you can use the
concerning API functions of the operating system. If you are using Windows,
look at this program:

I'm curious as to why you would need to do this. I've found that using time
stamps can efficiantly answer many questions when debugging a complex app under
development. Malicious intent? Why should the time stamp matter?

Of course I don't know why Craig wants to do this.
I myself often set the time stamp of a self-written program, when I've
finished a release version. When the program is say version 1.20, I'll
give it the time stamp
<current date> 01:20:00

Thanks Juergen,
That gives me enough with which to proceed. I will use SetFileTime in a
similar way. It's simple enough.

Malice? I'll let the insult slide, and answer your question directly ...
I have over 1,000 html files on my website. They are generated
programatically. When I do a run it might change just a dozen or so pages.
The second last thing I do is run a program (Euphoria, of course!) that
adds google analytics code to each page:
================================================
<script src="http://www.google-analytics.com/urchin.js"
type="text/javascript">
</script>
<script type="text/javascript">
_uacct = "UA-715xxx-4";
urchinTracker();
</script>
================================================
That process changes the date of the file to today.
The last thing I do is run a program (Euphoria, of course!) that
generates a google sitemap http://tinyurl.com/9a5nl. This program adds
the *date of last change* of each web page.
At present, the latter program will put today's date to pages in the
sitemap file (sitemap.xls) for pages that have been changed to add the
analytics code, but have not had their *content* changed.
I want to run the 'add analytics code' program in such a way that the
original page's date is left intact so that it doesn't give the wrong
date to the sitemap program.

Thanks for mentioning Google Analytics, I didn't know it before.
I visited their website, and it looks interesting.

It can be quite useful. Here's a snapshot of a report for one of my sites:
