Richard,
Thanks. I am astonished that this is possible.
I'm afraid I am missing something. I tried entering my data (my home
address--it appears that is what you did) in the USPS page
http://zip4.usps.com/zip4/
I then copied and pasted that source code into field 1 in LiveCode. (I
didn't see any reference to my data--my address--in that html text.)
I used your script in a button and obtained some html text in field 2.
But there is no reference in field 2 to my street address.
I don't mind working on the parsing to do the put and get, but I'm
sure I missing the ingredient where my data (address, city and St)
goes into field 1. I think that is what I am missing.
I don't see "visited=1&pagenumber=0 etc. anywhere in field 1 or 2.
Floundering,
Jim

Good news: you can use the post command for that.
Bad news: the result is HTML, so you'll need to parse out the
relevant
parts.
To test I made a stack with a button and two fields - here's the
script
for the button, using the URL derived from the HTML source of the form
element in that page:
on mouseUp
post fld 1 to url "http://zip4.usps.com/zip4/zcl_0_results.jsp";
set the htmlText of fld 2 to it
end mouseUp
Field 1 contains form element names and values, packaged up in the
name=value format used by both POST and GET:
visited
=1&pagenumber=0&firmname=&address2=620+moulton&address1=&city=los
+
angeles
&state=ca&urbanization=&zip5=90031&submit.x=48&submit.y=8&submit=Fin
Field 2 will contain the HTML once the request is returned. Now for
the
tedious parsing to get the parts you want....
