We describe this in Chapter 7, Collections. Multiple yield statements are permitted. For example: Copy class Test { static void Main( ) { foreach (string s in Foo( )) Console.WriteLine(s); // prints "One","Two","Three" } static IEnumerable<string> Foo( ) {yield return "One"; ...
CHARF is a fixed-length character string. You can use this datatype in VAR and TYPE statements to equivalence C datatypes to the fixed-length SQL standard datatype CHAR, regardless of the setting of the DBMS or CHAR_MAP option. When DBMS=V7 or V8, specifying the external datatype CHARACTE...
If you hold Ctrl, the labels in the file context view become clickable, so you can quickly go to the beginning of the current method, class, namespace, or any of the if/for/while statements. The “Explore outline” button opens the file structure in a separate Code Explorer window, so...
