  You need to put the array and procedure declarations together in a
public package, eg

    package Processing is

      type Blah is array (Integer range <>) of ...

      procedure Procname (N : in Integer; v1 : in Blah);

    end Processing;

and then the (private) body of the callee goes in the package body:

    package body Processing is
      procedure Procname (N : in Integer; v1 : in Blah) is
      ...
      end Procname;
    end Processing;

Then the caller will look something like
  with Processing;
  procedure Main is
    X : Processing.Blah(1 .. 10);
  begin
    Processing.Procname(17, X);
    -- or
    Processing.Procname(N=>17, v1=>X);

  The Ada language is not defined in terms of files, but rather in terms
of (separately compilable) "compilation units" - eg packages, library
level procedures, and some other stuff.  Some compilers (eg, GNAT) impose
a restriction that a single file can contain only a single compilation
unit.  I'm guessing you're using GNAT and that's why you get that
error message.
