Re: IWS and input parameters...

@Jon, so you are suggesting the pFilterDs input parm(s) be passed as a
character string and then parse them in the RPG.  That way I could still
use a GET.
That may work...

@Nadir, thanks for the links.  I reread them and I think I have a better
understanding.  One question, which I know I'm going to be asked is, why
are you using a POST to retrieve data?  I now understand I can do this.
But is the reason that there is a restriction in IWS (as there is more than
one parameter that is a structure) or is this a restriction of all web
service servers?

Thanks,

Rob
