Initialising stuff

["chris.danx" <chris.danx@ntlworld.com>]

Hi,

I need a variable (global) for a screen package (write to video memory) and
would like it to be initialised once and once only when the package is
"with"ed.

I can think of one way to do this...

package body xxx is
   ...
begin
   initialise screen stuff here;
end xxx;

but I'm unsure if this will work as I don't know the issues involved.  Will
this work bearing in mind the purpose of the package?

Is the following the same or similar?

package xxx is

    ...

    private
        type yyy
            is record
                abc : byte := 0;
            end record;
        a_yyy : yyy;
end xxx;


Any advice?


Thanks,
Chris
