  To start your program with a control bar the only thing you need is
to edit the rootlogon.C script to call your macro(C/C++ subroutine,
create a  C++ object for the pre-compiler C++ class etc ).
   You may try another approach just go to our Tutorials subdirectory
and try as follows:
           $ root demos.c
  Hope this helps.
