thanks, will that still exclude lowercase strings, i need to exclude both in my routine.
without doing this for example for every string:
 if Pos('ASSTRING', UpperCase(S))=0) then
 if Pos('astring', lowerCase(S))=0) then

I think it is not necessary:

if ( ( Pos('ASSTRING', UpperCase(S))=0) or ( Pos('astring', LowerCase(S))=0)) then

it is enough:

if  ( Pos('ASSTRING', UpperCase(S))=0) then

let see an example:

var
  BUpp:  Boolean;
  BLow:  Boolean;
begin
  BUpp := ( Pos('KYLIE', UpperCase(Kylie Minogue))=0);  // BUpp := False;
  BLow := ( Pos('kylie', LowerCase(Kylie Minogue))=0);  // Blow := False;
end;

It is not necessary the check both of variants because they are equal.
