How to handle data in TFunc with C++Builder(BCC32) When dealing with TFunc in BCC32(C++Builder 10.2). For example, suppose Delphi side has the following function. type Tproc_func = record {When TFunc is an argument as shown below. } function func1(func: TFunc<Integer, String>):String; end; implementation function Tproc_func.func1(func: TFunc<Integer, String>): String; begin Result := func(CurrentYear); end; The func1 function has an argument of TFunc.In this case, Delphi...

My Programming Language (Delphi) Can Do This joelonsoftware asks on his blog "Can Your Programming Language Do This?". Delphi 2009 introduces support for anonymous methods in Delphi language.
