Processing arguments in a string

Hi

The following code works when reading the arguments from the command line but fails when I try to read from a string. So this works

Code:
while [ -n "$1" ]; do
  case $1 in
        -dbversion) if [ "`echo $2 | grep -e '^-[a-z]'`" ]; then { echo "ERROR: missing value for '$1' (seen '$2')"; usage; exit 1; } else { shift; INPUT_VERSION=$1;   } fi ;;
        -type) if [ "`echo $2 | grep -e '^-[a-z]'`" ]; then { echo "ERROR: missing value for '$1' (seen '$2')"; usage; exit 1; } else { shift; INPUT_TARGET_TYPE=$1;   } fi ;;
        -host) if [ "`echo $2 | grep -e '^-[a-z]'`" ]; then { echo "ERROR: missing value for '$1' (seen '$2')"; usage; exit 1; } else { shift; INPUT_HOST=$1;   } fi ;;
  *)    echo "ERROR: unknown argument '$1'"; exit 1;;
  esac
  shift
done

but when I replace the line
Code:
while [ -n "$1" ]; do

witth
Code:
OPTPARMS="-dbversion 11.2.0.4.0 -type backup -host testhost"
 while [ -n $OPTPARMS ]; do

it only sees the "ERROR: unknown argument"

Can somebody please tell me what the problem is?
Many thanks

Please ignore the old code (back ticks, echo etc.).
