I have an app that sends an HTTP request to a server that returns
either a non-negative number if the request succeeds or an HTML

In my Rev script, I do:
put URL tURL into serverReturn
if char 1 of serverReturn = 1 then
put "User successfully created" into field serverReturn
put "Error encountered but no error checking implemented yet." into
(tURL is the URL to which I'm sending the request, just in case that's

IDE becomes completely non-responsive and I have to quit Revolution.
The app will save, so I haven't lost anything yet but this is really
