Please see the following example.

 Code:
$test=1

select
  ? "HEY THIS IS IMPORTANT!!!! I Shouldn't be here but I am"
 case $test=1
   ? 1
 case $test=2
   ? 2
 case 1
   ? 3
endselect


In the example above, The line right after the select is never run. Any number of statements can be put between the SELECT and the first CASE and they will all be ignored as well. I found this completely by accident, and while it was nice that Kix just kept working despite my syntax error, it would have saved me quite a bit of time trouble shooting the problem had kix just thrown a syntax error when the script was run.
