How to check if a variable contains a " or ` ?

Hello Group,

This is related to a question I had posed a few days earlier. I am
prompting the user for an input using "read". The user can enter any
number, alphabet or special character or any combination of these.
However, if they enter a " (double-quote) or ` (back tick), I would
like to do something else.

So for example, they could enter: 41" or 2` or just " or `. How would
I check to see if the variable contains a " or `?

We have AIX 5.2 and am using ksh.

Thanks for any suggestions.
S
