Please feel free to update your posts as you have done with your OP, but it is considered polite to include a note to the effect that an update has been made.

Also: Please use  <c> ... </c> or  <code> ... </code> tags around code, data and input/output. (Please see Markup in the Monastery and Writeup Formatting Tips.) Otherwise, something like 1, 2, 3, 4 looks like a hyperlink to... somewhere... maybe the Delta Quadrant?
