Ok then, i use the clause use in my .ada for my package ads, it's
working, 
but i don't understand why i need to put a use clause for only this king
of operator ?

For the rest of my .ada program  i only precede each thing by the .ads
package name 
Ex : package.var := xxx;

Thanks
Dominic

You want a "use type" clause on the pointer type.

Yes, "/=" is allowed on pointers, but this operator is implicitly
declared at a certain place in the program, and you need to make it
directly visible in order to call it.
