There are two problems here. 1) you can only take slices of one
dimensional arrays (yes, that is annoying). 2) A and C are of different
(anonymous) types so the compiler will point that out if you try to assign
a chunk of one to the other.
If you do
type Rows is array(1 .. 4) of integer;
a : Rows;
c : array(1 .. 2) of Rows;
then any of
a(1 .. 4) := c(1)(1 .. 4);
a := c(1);
a(3 .. 4) := c(2)(1 .. 2);
are ok.
or
type Rows is array(integer range <>) of integer;
a : Rows(1 .. 4);
c : array(1 .. 2) of Rows(1 .. 4);
d : array(5 .. 6) of Rows(11 .. 25);
a(1 .. 2) := d(6)(11 .. 12);
will also work.
