If you want an absolute path then this should help you out:

#!/bin/tcsh -f 
set called=($_)

if ( "$called" != "" ) then  ### called by source 
   echo "branch 1"
   set script_fn=`readlink -f $called[2]`
else                         ### called by direct execution of the script
   echo "branch 2"
   set script_fn=`readlink -f $0`
endif

echo "A:$0"
echo "B:$called"
set script_dir=`dirname $script_fn`

echo "script file name=$script_fn"
echo "script dir=$script_dir"
