Any function that accepts only one parameter can be called as if it were a property, and this applies to built-in system functions, your own custom functions, and even .NET methods alike. Instead of doing it like Report50001.SetDefaultPostingDate(101015D) you can always do it like Report50001.SetDefaultPostingDate := 101015D. Of course you can improve semantics of your code significantly if you simply call the function PostingDate instead of SetDefaultPostingDate, then you can just write Report50001.PostingDate := 101015D;
Remember – this works for all function types, even .NET method calls.
