Thanks Benjamin,
I noticed that there are quite a few resellers in Europe and other parts of the world. If there are any in Australia they're keeping themselves nicely hidden. Since Sybase put it into their store we've always purchased extra copies online and dowloaded them. I guess SAP just don't want people buying PowerBuilder from them any more.
I'm afraid the lack of response to my question is a bit disheartening. I know there was something published about SAP's intentions on their website but I can't find it now and it seems no-one else can, or they prefer to believe things they've heard, those being deniable, to be fact.
As we're now thinking about upgrading/replacing our application it is a business imperative that we have absolute confidence in our choice of tools for the next ten years. SAP just don't seem to get that about their customers.
Thanks again, Paul
