Is Result variable defined from first line in a function?

Question

I need a clarification of this case.

According my tests the Result variable is defined to: Boolean=False, Integer=0, String=\'\', Object=nil etc from the first line.

Answer 1

No, Result has no (guaranteed) default value. It is undefined unless you give it a value. This is implied by the documentation, which states

If the function exits without assigning a value to Result or the function name, then the function's return value is undefined.

I just tried

function test: integer;
begin
  ShowMessage(IntToStr(result));
end;

and got a message with the text 35531136.
