(I guess Jonas intended to avoid a complicate answer, but let me complicate it for you ;-) ... and the AnsiString has refcount = 1. If you access the string through a by-value parameter or assign it to a temporary variable, you're safe too. (unless, of course, some screwed code change the contents of the string in-place - e.g. with a typecast to pchar or some other pointer) -Flávio _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
