Delphi Array Constants
Delphi Const Array Multidimensional
So far, we have only seen lists - single dimensional arrays. Delphi supports arrays of any numbers of dimensions. In reality, a multidimensional array is a collection of arrays - each element of the first array is another array. Each element of that array is in turn another array and so on.
[] [] [] [] 14.4.6 In Object Pascal or Delphi mode, Free Pascal supports the Array of Const construction to pass parameters to a subroutine. This is a special case of the Open array construction, where it is allowed to pass any expression in an array to a function or procedure.
The expression must have a simple result type: structures cannot be passed as an argument. This means that all ordinal, float or string types can be passed, as well as pointers, classes and interfaces. Hindi movie andaaz akshay kumar song. The elements of the array of const are converted to a special variant record. Procedure Testit (Args: Array of const); Var I: longint; begin If High(Args).
S:=’Ansistring 1’; T:=’AnsiString 2’; Testit ([]); Testit ([1,2]); Testit ([’A’,’B’]); Testit ([TRUE,FALSE,TRUE]); Testit ([’String’,’Another string’]); Testit ([S,T]); Testit ([P1,P2]); Testit ([@testit,Nil]); Testit ([ObjA,ObjB]); Testit ([1.234,1.234]); TestIt ([AClass]); If the procedure is declared with the cdecl modifier, then the compiler will pass the array as a C compiler would pass it. This, in effect, emulates the C construct of a variable number of arguments, as the following example will show.
