rc.d_scripts/start_up_files

Hi
I'm having trouble getting a few services to start automatically.  I'm using
RH 7.2 and I'm using csh as my login shell.  I've been trying to accomplish
this by creating a rc.d script, but can't get it working.  The command in my
script works properly when I test it in a terminal but doesn't run when on
restart/relogin.  Does anyone know of a good resource I could access for
info on how this process is structured?  I placed the script /etc/rc2.d  Do
I also need a reference to the script in my /.cshrc file?
Thanks very much in advance.
