Hi Peter - thanks for your comments. I wonder if you would mind expanding on
your ideas just a little. I can see what you mean about the hidden frame,
but as to 'sending its contents', and 'trip some event', I'd like to hear
just a little more.

I came up with an idea of my own: Assume 'Frame_A' is the master, which has
a link to load 'Frame_B' with page_B.html. I can see page_B.html as
containing the following:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html><head>
<SCRIPT SRC="data_processor.js"></SCRIPT>
</head>
<body  onload="data_processor()">
<SPAN ID="data">datadatadatadatadatadatadata</SPAN>
</body></html>

and this should work, but ideally, I'd like the file to contain only data,
not the headers/footers as well, though this may be impossible.

Another idea: I wonder if I could use

<FORM name=F1 action="javascript:data_processor();"><input type="file"
name="data"></FORM>

to let someone locate a datafile on their PC, and get it processed. Has
anybody tried this ?
