The fact that Borland regarded "$FF..FF" as a 2's complement
representation and not as a base-16 representation of an integer is
not really what I would call "Pascal spirit". As a matter of fact,
"Borland mess" would be more appropriate. :-)
I always avoid such imponderabilities by using fillcha

Agreed.

Yes, indeed. That will always work and is completely safe.

program:
program Project1;
const
MyVar : UInt64 = $; // 4 x 2 Bytes or 4 Words
begin
end.
In Delphi this compiles without
15 matches
