Hi Allen,
>>My manager "heard" that PowerBuilder was no longer being supported after 2015.<<
I hear that very often! And I am very sad about it, because these rumors come from people right out of our community.
I spend a lot of my spare time in fighting this fire that is lit again and again without any proof!
I spoke with senior SAP managers and saw and heard what they said at our PBUGG Meeting last year. From this I can say that PowerBuilder is now a SAP product and has the same support and maintenance that SAP gives to all their other products!
I just spent 4 hours in supplying material to one of our UserGroup Members who is in the same trouble as you!
If you go to Bruce’ blog http://brucearmstrong.blogspot.de/ the first video More video from the PowerBuilder User Group Germany http://vimeo.com/81870887 you find after 13:00 min Robyn Chan speaking of 8 years maintenance.
SAP has a general paper about their release and maintenance strategy called “SAP Release Strategy” See: http://scn.sap.com/blogs/sapreleasestrategy (but you need a S-Id).
If you don’t have a S-Id you can look at what’s public for Business Objects. http://scn.sap.com/docs/DOC-31244 and Chrystal products http://scn.sap.com/docs/DOC-44670?rid=/webcontent/uuid/c018fb0e-8724-2b10-c489-9b8333e5e0f9. I think you can expect at least the same for PowerBuilder.
