start an application on startup

["Fred J." <phddas@yahoo.com>]

Hi
 I have a C++ code which fires, does its thing, and waits for input.
 I need to get it up and running automatically from boot up.
 I am able to open xterm with the following line 

in  .bash_profile
# run the following programs
 xterm &
 
  my C++ application "proj" is in $HOME/path/to/proj

in .bashrc 
 path/to/proj

which is read by xterm every time it is fired, it works but then when I open another xterm to do othere things, it fires my proj which is not what I want, I want only one instant of the proj running.

thanks
 thanks
