In the "stringscommented.pas" collection I found this nice function:

function StrPosRelative(const Str, Token: String):UInt8;
var
lvar1, lvar2: tPIS;
begin
lvar1.recPtr:=StrStr(Str, Token);
lvar2.recPtr:=@Str;
StrPosRelative:=lvar1.recInt-lvar2.recInt;
end;

Unfortunately I couldn't find the "StrStr" function in any library.

Do you have any hint for me to use this function?

Regards, Reinhard.
