   Hi Mike,

   Your observations are right and now the program works perfectly.
   Thank you so much!

   > Well, I built the parameter part of the string with the function
   "http_url_encoder_addvar_s", maybe the problem is there?
   The way you retrieved the data is a problem. REQ does not have blanks
   in it. Therefore an ordinary %trim is leaving x'00' attached. The
   length of URL is 1000 and the %trim has no effect.
   One fix is this:
   url = %trim(url) + %trimr(req:x'00');
   Another is this...
   data being a varying length field
   data = http_url_encoder_getstr(Enc);
   Another is to use the webform support (EXAMPLE12)
     form = webform_open();
     webform_setVar(form: 'query': %trim(queryString));

     uri ='http://api.wunderground.com/auto/wui/geo/ForecastXML/+
           index.xml?query=' + webform_getData(Form);
     webform_close(form);
