DEC Ada and packages

["Zane H. Healy" <healyzh@shell1.aracnet.com>]

I'm trying to teach myself Ada using DEC Ada on OpenVMS.  I've currently run
into a bit of a problem.  How on earth do you deal with Packages?  I've been
reading through the DEC Ada manuals and can't find anything.

As I understand it I should be able to put have a file 'powers.ada' have
something like the following in it (taken from an excellent tutorial I found
online):

package body Powers is
        function Square (Arg: Integer) return Integer is
        begin
                return Arg * Arg;
        end Square;

        function Cube (Arg: Integer) return Integer is
        begin
                return Arg * Square(Arg);
        end Cube;
end Powers;

Then call it from another file with a Proceedure.

However, I end up with the following results:

$ acs
ACS> load powers
%ACS-I-CL_COMPILING, Invoking the Compaq Ada compiler
ACS> compile powers
1 obsolete unit

%ACS-I-CL_COMPILING, Invoking the Compaq Ada compiler

    4   package body Powers is
........1
%ADAC-E-CL_SPENOTFOU, (1) Specification for Powers not found in library
at line number 4 in file MONK$DKB500:[HEALYZH.WORK]POWERS.ADA;4
%ADAC-E-ERRRECOMPILE, Errors recompiling package body Powers in file 
        MONK$DKB500:[HEALYZH.WORK]POWERS.ADA;4
%ADAC-E-ENDDIAGS, Ada compilation completed with 1 diagnostic

1 unit compiled in 00:00:00.14

%ACS-E-CL_ERRDURCOM, Errors during compilations
ACS> load play
%ACS-I-CL_COMPILING, Invoking the Compaq Ada compiler
ACS> compile play
%ACS-E-CL_UNKREFUNI, PLAY depends on unit POWERS, which is not in the
library
ACS> 

So how on earth do I get POWERS into the Library?  I'm sure I'm missing
something obvious, but what?
