Also depends of platform... program tests; var s, s1, s2: ansistring; begin SetLength(s1, High(int32)); SetLength(s2, High(int32)); WriteLn(Length(s1)); WriteLn(Length(s2)); s := s1 + s2; WriteLn(Length(s)); end. Works as 64 bit Windows program: 2147483647 2147483647 4294967294 But gets "Runtime error 203 at $00404A01" on 32 bit Windows (out of memory). I did not actually know, that string length was 64 bits on 64 bit platform (at least on Windows), because even uint worked. uint32 version of same code generated warning at compile time. And uint32 version of same code results in strings with length 0. Because sizeint is signed. I do not have access to 64 bit Delphi, but Embarcadero RAD Studio Athena documentation claims, that there ansistring length is limitud to "~2^31 characters". And there is no implication, that 64 bit has different maximum. -- Virgo Pärna virgo.pa...@mail.ee _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
