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.
