Is it correct that an external variable can be declared in GPC as follows: var eV: integer; external; asmname 'eV';
Yes. In future releases, this statement might be var Foo: Integer; external name 'Bar';
Is there a similar construct to declare external constants ('extern const' in C) ?
Not as constants. In C: baz.c const int _c_bar = 42; In GNU Pascal (future release): baz.pas var Foo: const Integer; external name '_c_bar';
(As far as I remember)
A disadvantage of those constants is, that you cannot use them in a `case' statement.
