Getting the name of the varray

Question

Getting the original name of the Varray:
9.2.0.6
I have a simple procedure which does work but I would like to tighten it up.
procedure printVarray(u IN numUsed, varrayName IN VARCHAR2 DEFAULT NULL) is
begin
IF varrayName IS NOT NULL THEN
     dbms_output.put_line('Working on Varray ' || varrayName);
     for i in u.first..u.last loop
dbms_output.put_line('u[' || i || '] = ' || u(i).num || ' '
|| u(i).cnt);
end loop;
          dbms_output.put_line(' ');
END IF;          
end printVarray;
assuming u1 , u2, u3 & u4 are initialized and has values then
I can from a block do
begin
printVarray(u1,'u1');
printVarray(u2,'u2');
printVarray(u3,'u3');
printVarray(u4,'u4');
end;
and get the output I would expect:
... lines not show above
Working on Varray u3
u[1] = 1 2
u[2] = 2 3
u[3] = 3 4
u[4] = 4 3
Working on Varray u4
u[1] = 1 1
u[2] = 2 2
u[3] = 3 3
u[4] = 4 3
My question is how can I do away with passing the name of the original varray
to the procedure printVarray and still have it print the name of the original
varray?
Thanks

Not possible in PL/SQL dynamically if you're thinking alone those lines. You will need to pass a separate (manual) varchar2 parameter containing the name of the variable - as your printVarray() proc is currently doing.
You can simply change the DBMS_OUTPUT to:
dbms_output.put_line( varrayName||'[' || i || '] = ' || u(i).num || ' '
|| u(i).cnt);
