I'm relieved to hear that . I've not used 12.6 but I said it was "implicit" from what I'd read - that was from an SAP site, "If you want to deliver both 32-bit and 64-bit versions of your application, you should use separate projects and separate folders for the deployed output." My mistake; I read "project" and was thinking "workspace".
But the question remains, how will one be able to develop (or deploy) in PowerBuilder using Windows 8 and connect to MS SQL Server beyond MS SQL Server ver 2008? Am I missing something here, too?
