The problem is that I have two streams of data within my program that 
are almost the same I just have to safe them in two random access 
buffers. These two buffers will be filled with two complete different 
sets of data.
The difference between these data streams is not the program part where 
most of the buffering  is done. That part is identical between the two 
data streams. So I wanted to use the same procedures and functions where 
possible.
I already have a generic package for such a buffer (instantiations can 
be made for all kind of types(f.i integers, unbounded_Strings). Do it is 
logical that I want to use that package with two instantiations for the 
same type.
