#    AUTHOR  - F.Majaess
 
#hd  PURPOSE - "checker" code is used to check on parameter values by echoing
#hd            the elements in "chkrl" parameter list.
 
#   * make sure arguments list variable "chkrl" is initialized...
 
chkrl=${chkrl=}
 
#   * The following code deals with echoing the parameters in "chkrl" 
#   * (provided "chkrl" is not empty).
 
if [ -n "$chkrl" ] ; then
  
  i=1 
 
#  * echo each argument in "chkrl"... 
  
  for prmtr in $chkrl
  do
      
   case $i in
    1) echo " Security check for $prmtr: " ; echo " " ;;
    *) echo " $prmtr " ;;
   esac
 
   i=`expr $i + 1`
  
  done
 
  echo ' if everything is ok, enter <CR> '
  echo ' to abort, type ^C or ... '
  read prmtr
