The issue you're running into is called variable shadowing. Reading up on that should give you the answer to your problem. -- Leif Roar Moldskred But, variable shadowing is about the instance and local || local and scope specific. I have read the articles again after you asked me too. No luck on the exact problem I am mentioning. I am talking about inherited variables. there is i1, i2 and i3 in the super class with a method printall. there are the same 3 variables in the derived class but there is no printall method in the sub class. When printall() is invoked from the derived class's object, it still prints the super-class's values. And, if this is reasonable, what is the method by which I can get: 40, 50 and 60 as the output from printall() when I invoke it using a derived class's object? -Venu --- BBBS/Li6 v4.10 Dada-1 * Origin: Prism bbs (1:261/38) --- Synchronet 3.16a-Win32 NewsLink 1.98 Time Warp of the Future BBS - telnet://time.synchro.net:24
