Interesting. Why not:
function foobar() {
// Note the use of the "new style" function names
var response = null;
do {
sendPageAndWait("showform", {});
// Collect request parameters here
sendPageAndWait("askforconfirmation", { /* ... field values ... */ });
response = input("request-param","confirm"); // or
request.getParameter("confirm");
} while (response == null);
sendPage("thankyou", {});
}
