File.New behavior with SCC in PowerBuilder.NET

What happens when the library (PBL) is not checked out, and I try “File → New” ? Or more generally, how does “File→ New” interact with Source Code Control systems…
Short Answer:
The “File → New” action may fail, depending on how “automatic checkout” is set.
The attached document (PB125_SCC_Note1.pdf) contains the three scenarios for how “Automatic Checkout” may be set along with screen shots of the (current) behavior in PowerBuilder.NET.
The test case is for Microsoft’s Team Foundation Server (TFS) but everything should be the same for other SCC providers.
