 // Smallint is a two-byte (16-bit) signed integer var I: smallint; begin // its maximum value is: 01111111 111111112 ASM mov I, 0111111111111111b end; showmessage (inttostr (I); {32767} // the minimum value is: 10000000 000000002 ASM mov I, too many else 000b end; showmessage (inttostr (I); {-32768} end;

 // Int64 is 8 bytes (64-bit). I cannot test it for the moment.
