I do not know if this is the best way.  This is the beginning of building a bigger script. I am trying to see if a variable is a digit (3 digits between 0-9) in a ksh script. Do I need to verify the variable before I get into the IF statement?

for list in `grep -l '\*\*\*\*\*' ??????`
do
    varLine=`head -l -n 1 $list`
    varDocType=`echo "$varLine" | cut -c23-25`
    if [ varDocType -eq +([0-9]) ]
    then
        echo "Filename=$list Document Type=$varDocType"
    else
        echo "Not Correct Type"
    fi
done
