Example of calculating a simple checksum.

Beispiel, wie eine einfache Checksumme berechnet werden kann.

}

function CalcStrChecksum(s: string; zerobased: Boolean): Longint;

var

i: integer;

L: integer;

begin

Result := 0;

l := Length(s);

if l > 0 then

begin

for i := 1 to l do

if zerobased then

Inc(Result, Ord(s[i]) - 65)

else

Inc(Result, Ord(s[i]));

end;

end;
