Unable to store "-e" in variable ??????

Thanks corona. It works, but still
echo -- $str ==> -- -e
Is it posible to give just teh stored value "-e" or so we need to cut and get the variable.?
---------- Post updated at 04:47 PM ---------- Previous update was at 04:29 PM ----------
I finally settled for :
str="-e"
echo .$str | sed 's/\.//1'
-e
So wherever I want to echo variables (even if it contains -e/-n/-E ) I used the above & it works fine. Thanks corona !!
