Back in 2003, Sybase introduced CodeXchange, an online forum that allowed developers to share code samples and collaborate on open source projects. Unfortunately, in 2009 Sybase decided to shut down that system. The PowerBuilder code samples that had been uploaded tp CodeExchange did eventually show up again in a CodeXchange section of the PowerBuilder wiki on SAP's SCN. Appeon also obtained permission from many of the authors to post those same PowerBuilder samples on the Code Samples section of the Appeon site.
