type LongCard = Cardinal attribute (Size = BitSizeOf (LongInt));
LongCard is an unsigned integer type which is longer than Cardinal. On some platforms it is 64 bits wide and thus has a range of 0 .. 18446744073709551615.
LongCard in GNU Pascal is compatible to long long unsigned int in GNU C.
There are lots of other integer types in GPC, see Integer Types.
LongCard is a GNU Pascal extension.
program LongCardDemo; var a: LongCard; begin a := 42; WriteLn (a) end.
