Byte { built-in type }
Byte is an unsigned integer type which is one "unit" wide.
On most platforms one unit has 8 bits, therefore the type is named
"byte" and usually has a range of 0..255. (It is the same
as ByteCard.)
Byte in GNU Pascal is compatible to unsigned char
in GNU C.
There are lots of other integer types in GPC, see Integer Types.
Byte is a Borland Pascal extension. (For something equivalent in
ISO Pascal, see Subrange Types.)
program ByteDemo; var a: Byte; begin a := 42; WriteLn (a) end.
