and then instantiate something where you need it.

It's pretty obvious what's wrong.  What did your compiler tell you?

please help me get it all right
my question is i need to write an ado that implement the generic
package.
in the ado i have a generic function that accept instant of the
generic
package.
i dont understand where to create the instant generic package in the
ads file or the adb file? and how do i pass it to the generic
function?
do i have to write generic section in the ado to create the generic
package instant?
this is what i wrote( i get subtype is reqiured in thus context)
ads:
----------------------------------------------------------
with  generic_package;
generic   
   with package new_generic is new  generic_package(<>);    
package use_generic is
      generic
      procedure generic_procedure(str:String;a:in new_generic);


end use_generic ;
----------------------------------------------------------
adb:
package body use_generic is
   procedure generic_procedure(str:String;a:in new_generic) is
   begin
      something........;
   end  generic_procedure;
end use_generic ;


thanx

What on Earth is an "ado"?

Surely you don't want to pass an "instant", because it will be gone just
after you passed it ;-)

Now serioulsy, what I think is the fundamental piece of Ada knowledge
that you're lacking is: packages are not objects. So, you cannot pass
packages to subprograms via parameters. You can of course pass objects
associated with *any* package including your *instance* e.g.

Op (X : Package_Instance.Object)

Perhaps: Abstract Design Object?


Or it can be something boring as:

http://www.w3schools.com/ado/ado_intro.asp
What is ADO?

    * ADO is a Microsoft technology
    * ADO stands for ActiveX Data Objects
    * ADO is a Microsoft Active-X component
    * ADO is automatically installed with Microsoft IIS
    * ADO is a programming interface to access data in a database

I know, but any of these is an "ADO", not an "ado" ;-)

Ah.

Webster:

One entry found for ado.
Main Entry: ado
Pronunciation: &-'d�
Function: noun
Etymology: Middle English, from at do, from at + don, do to do
Date: 14th century
1 : fussy bustling excitement : TO-DO
2 : time-wasting bother over trivial details <wrote the paper without further ado>
3 : TROUBLE, DIFFICULTY


Much ado about nothing.
