Hi,


When i try to do this :

x := ppp (x,z); --where x is a access type and ppp return a access 

if (x /= null) then  --the line where the compiler stop

    zzz (x,z);
else   
    aaa (q,r);
end if;


I got this error :

gerer_location.ada: Error: line 136 col 23 LRM:8.4(1), 
Binary operator "/=" not directly visible, use clause or conversion
might be needed 


The operation "/=" should be permit on pointer, then why i got this
error ?

Thanks
Dominic
