Hi, we are looking to hire a graduate programmer to help out with our Powerbuilder and API development. It's bee a while since I learnt Powerbuilder, so I'm wondering if anyone has any recommendations on training a programmer new to Powerbuilder. They would need to get up to speed with both Powerbuilder and SnapDevelop.  I'm guessing any dot net core training would be suitable for learning to use SnapDevelop but if there are any SnapDevelop/.Net DataStore specific resources people can recommend that would be great. Also, I know there is a course on Appeon U, is that the best place to start for someone wanting to learn Powerbuilder?
