x=$#
while [ $x-ne 0]
do
eval echo \$$x
x=`expr $x- `
done

error:
line 2: [:-ne: unary operator expected

Code:

while [ $x-ne 0 ]

(space after 0 and before ])

You will probably need to add spaces between x and -ne as well as the before mentioned spaces by the brackets.

Code:

while [ $x -ne 0 ]

Hope this helps.
