Hi,

I'm using {$LONGSTRINGS ON} to use a string variable like ansistring.

In this example, if I uncomment the s1 variable I got "Error: Constant strings can't be longer than 255 chars", but if I uncomment the s2 variable (formed by concatenation of strings) the project compiles perfectly.

program testLongString;
{$LONGSTRINGS ON}
var
  s1, s2: String;
begin
 // test strings with more than 255 characters
//  s1:= '1         1         1         1         1         1         1
1         1         1         1         1         1         1         1
1         1         1         1         1         1         1         1
1         1         1         1      end';

{

  s2:= '1         1         1         1         1         1         1

1 1 1 1 1 ' +
'1 1 1 1 1 1 1 1 1 1 1 1 ' +
'1 1 1 1 1 1 1 1 1 1 1 1 ' +

       '1         1         1      end';

}
end.

I need use the s1 variable way because I'm receiving in a string a value read from a BD.

I also tried compile with "-Mdelphi", but the error stills the same.

Thanks in advance,

In this case, "constant string" is a character sequense between two ''. If you receive a string value in run-time, all must be OK.
