That all sounds correct.
If you look at the code at the end of Init you can see what it does:
if false is s = GetFile(args)
s = args
s.Eval()args in your case should be “server.go”
It sounds like GetFile is failing and it is trying to Eval “server.go”
You can run the above code (or just GetFile) from the WorkSpace and see what you get.
Are you sure you’re typing the file name correctly, and that it’s in the current directory?
