RE: RPG UI Frameworks was->RE: Fw: Enhancements to RPG

Hi Joel,
Welcome back!

I think it is something that can be easily written. There are a couple of APIs
that allow you to load a service program dynamically and then call a
subprocedure in that service program. Having a generic subprocedure caller would
be challenging if written in RPG IV, but I could probably do it in C.

I know I don't post here much anymore (I don't feel so welcome since I
became a .NET developer), but this intrigued me:

However, a Web/Browser interface can already do event-driven stuff via

regular CGI calls to RPG or any language. What would be beneficial is the
ability to "AJAX to" a subprocedure directly rather than only to a
program. I'm
not certain if that's much better from a performance standpoint than just
leaving a CGI program active in its A/G and reactivating it, but it would
be
cooler. :)

I had an idea last year (but no time to work on it) that may address this.
Assume the subprocedure you want is in a Service Program. Now assume there
was a tool that would allow you to create Webservices from Service programs
(like NuSOAP for PHP). Essentially, a Webservices Wrapper for Service
Programs, complete with WSDL support that delivered SOAP messages containing
the return values. Assuming that you can "AJAX" to a webservice, wouldn't
this do what you suggest here?
