type ByteCard = Cardinal (BitSizeOf (Byte)); |
`ByteCard' is an unsigned integer type which is one "unit" wide. On most platforms one unit has 8 bits, therefore the type is prefixed "byte-" and usually has a range of `0..255'.
`ByteCard' in GNU Pascal is compatible to `unsigned char' in GNU C.
There are lots of other integer types in GPC, see section 8.2.3 Integer Types.
`ByteCard' is a GNU Pascal extension.
program ByteCardDemo; var a: ByteCard; begin a := 42; WriteLn (a) end. |
