Thanks that works great. I got:

Code:
while ! TRUE
do
  print "enter a datafile number: "
  read DBFILE
 
  if [[ -n $DBFILE ]]
  then
  eval "
    if [[ $DBFILE = ?($NEW_FILEID) ]]
      then
      DBFILE_VALID=true
     else
       print "invalid number"
     fi
     "
  else
   DBFILE_VALID=false
  fi
done


The file numbers are generated dynamically thru sqlplus and placed into $NEW_FILEID. It all works great.

If I enter a character like !, ` , or # in response to the question "enter a datafile number?" it will stop the shell script and exit. How do I trap for those special characters?

thanks.
