How-to check for ksh88 or ksh93?

Dude!Jul 7 2011 — edited Jul 9 2011
Hello,

I'm trying to find out whether the current running command shell interpreter is ksh88 or ksh93.

I have come up with the following coding so far: 
[ "`echo "\c" | grep c`" ] && echo ksh93 || echo ksh88
But can I really use the above to check if a Korn shell is 88 or 93?

Thanks!
