Yep, makes sense, especially if they sell those zip+4 lists.
Kind of related, has anyone had any experience with selecting zip
codes based on a given zip code and a radius from it? A mailing list

function to have. I'm
In general.
Open the web page, view source, find the form tags and for every variable
within the form tags, create a tag= value. If there are hidden fields and radio
buttons, just look at the HTML specs to see how to format those tags in the GET
statement. Make sure you URL encode the data
As Kee Nethery said, the answer to the names of the variables is in
the FORM ... /FORM section of the starting web page.
Spaces are not allowed in the GET string, thus the '+' char.
You could use LCode urlEncode(GetString) to be sure all chars
necessary are converted before sending a GET to

This may be naive, but is it possible to do this from within LiveCode
by script?
Good news: you can

Richard,
Thanks. I am astonished that this is possible.
I'm afraid I am missing something. I tried entering my data (my home

- this method has a limit of about 1000 chars and is sent so that a
program sniffing packets
The POST is a more capable method that sends the web page address
another message that can contain a variety of encoded data. - this
