RE: call an rpg program to return a true/false value in javascript -- WEB400

As for the event, the HTML generated by the RPG could include a javascript
that informed the window that opened it that the cookie was now available,
it would then close.

Well I wasn't thinking of RPG being called, but consider this.

You use the target (or whatever that keyword is) to open the hRef in a new
windows. That hRef calls the CGI program and displays the HTML generated bye
the CGI. Then you have a window with your user selection choices or whatever
it is in there. Or perhaps nothing.

The CGI program writes the cookie out, and also sends some HTML to the
StdOut. That HTML is simply a short HTML that will close itself (hence
closing the new window) and therefore return you to the call's window.

Not the part I'd have to lookup...
Upon resuming in the original window, there is probably an event that would
need to be detected and a second JavaScript could be used to then read the
cookie written by the RPG program. I'm thinking of an OnFocus() event or
something like that.

Something like that might work.
