want to use C shell

[Chris Job]

Hi folks...
I have an application the needs the C shell (tcsh to be exact). I've
created a user account that uses tcsh instead of bash.  I trying to add
the application's bin directory to the PATH by typing the following in a  
.login file 
PATH ${PATH}:/appl/bin
When I log out and log in again and echo the PATH, /app/bin does not show
up.  Can anyone tell me what I'm doing wrong or better yet what I should
do to get is right?

Thanks
Chris
