LongBool = Boolean attribute (Size = BitSizeOf (LongInt));
The intrinsic LongBool represents boolean values, but occupies the same memory space as a LongInt. It is used when you need to define a parameter or record that conforms to some external library or system specification.
LongBool is a Borland Pascal extension.
