Integer { built-in type }
Integer is the "natural" signed integer type in GNU Pascal.
On most platforms it is 32 bits wide and thus has a range of
-2147483648 .. 2147483647. Use it whenever you need a
general-purpose signed integer type.
Integer in GNU Pascal is compatible to Int in GNU C.
There are lots of other integer types in GPC, see Integer Types.
In ISO Pascal, Integer is the only built-in integer type.
(However see Subrange Types.)
