Here's how to restore your tcsh settings to the default (actually, a better condition than the default):

echo "source /usr/share/tcsh/examples/rc" > ~/.tcshrc

source ~/.tcsh (This will load Apple's tcsh configuration example and provide you with a fresh ~/.tcsh file with which to experiment/begin configuring.)
