Integer { built-in type }
Integer is the “natural” signed integer type in GNU Pascal.
On some 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.
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.)

a: Integer;
