-And, when editing session startup files like ''.bashrc'' or ''..tcshrc'', it is always a good idea to test them in your current session, before logging out to have them in effect for your next login. The reason is, that mstakes are easy to make, and many login environments are not very forgiving, ending the login eattempt with an error if there is an error in the startup files.  +And, when editing session startup files like ''.bashrc'' or ''.tcshrc'', it is always a good idea to test them in your current session, before logging out to have them in effect for your next login.

 +Yet another methoud would be, to include the setenv (or export) commands and the source command into a small text file or script, and load that file when you want to activate the MESA environment, e.g create file ''mymesa'' containing:
 +  setenv MESASDK_ROOT /net/vdesk/data2/your_username/MESA/mesasdk
 +  setenv MESA_DIR /net/vdesk/data2/your_username/MESA/mesa-r10398
 +  source $MESASDK_ROOT/bin/mesasdk_init.csh
 +And when you want to active your MESA environment, type ''source mymesa''. Like the method with the ''alias'', this method makes sure the environment is only loaded when needed, so it will not interfere with normal logins or with other programs.
