KSH Script

Hello,

I have an issue with the error returned on a simple ksh script.

What I am doing is the following from a command line:

if [ `echo $foo` ]
then
echo Variable FOO exists
else
echo Variable FOO does not exist.
fi

This works for the most part other then when foo does not
exist. If I have unset foo then I get this message when typing
in the above lines:

ksh: foo: 0403-041 Parameter not set.
ksh: foo:: 0403-012 A test command parameter is not valid.
Variable FOO does not exist.

Is there a way to NOT receive that message?

Thanks for any assistance in advance.

-Burgel
