[fpc-pascal] Type helper for array

[Vojtěch Čihák]

@ But the question is whether he want to set the array to empty or if he wants to clear the array's contents without changing the size.
 
The second is right but it was not the point. "Clear" is just one example of several methods I want to encalupsate into TBuffer.
I decided use the type helper now. Another solution is class:
 
TBuffer = class
  Data: array of Single;
  procedure Create(ASize: Integer);
  procedure Clear;
end;
 
So I would call aBuffer.Data[3]:=5; instead of aBuffer[3]:=5;.
Thanks

*shrugs* That's also a way. Bit the question is whether he want to set the array to empty or if he wants to clear the array's contents without changing the size.
