Question -z in ksh issue

Hi,

Can any body please tell me what does -z do in ksh?
I need to understand what does below code do?

FILE_LIST is an array which store multiple number of files...

Code:
if [[ -z ${FILE_LIST[$j]} ]]; then
                echo "EVDO file not found
fi

I hope I'm clear on my query

Code:
 
man test

Code:
 
     -z string                   True if  the  length  of  string
                                 string is zero.
