8/20    I've been able to do "echo $JAVA_HOME/abcd:$JAVA_HOME/xyz" for many
        years but today I get an error message regarding a bad modifier. Now
        I have to explicitly say "echo ${JAVA_HOME}/abcd:${JAVA_HOME}/xyz".
        What the hell changed? I still use tcsh.
        \_ Perhaps : colon is a modifier, hehe. What did you change?
           What is JAVA_HOME? Show exact transcript of your terminal session
        \_ You changed shell?
