SizeOf(Buffer);
What if Buffer is changed from a static array to a dynamic array.
Putting the type name there instead wouldn't help any. The size of a dynamic array is always 4.
SizeOf doesn't work for dynamic arrays.
Another reason why not to use SizeOf like that.
One main reason I started to program in TurboPascal and later Delphi is that it's more easy to change code in Delphi without running into all kinds of stupid changes and/or bugs everywhere, sometimes some smartness is needed as well.
Using SizeOf on static buffers is clearly not very smart <- bug prone.
OK. So don't do that. Nothing to do with the issue at hand, though.
