Note that you can only have 9 parameters passed like this ($1 to $9).  If you try to refer to $10 in your script, it will use the value of $1 and append a zero to that value.

To refer to parameters 10-255, you need to enclose them in braces, eg:

${10}
${11}
..
${255}

The only shell that doesn't support this is the tradition bourne shell.
