Hi Hans,

Yes.  Thanks.  Usually I do not do this.  However, in this
particular bit of code, I have a few lines that do the exact
same thing except they use different sizes toward li_s.

Rather than a comment, though a comment would work as well,
I simply placed the cast for my own benefit so that I may pick
out the correct sized line.

As you probably know, not always does a comment change when
the code changes.  After a few changes, the comment might
be completely different from the line.

Thanks all for the comments.  A little mistake as the
one I made before was fixed after a little sleep.  It was
just a bit late to retract the post :)

Not everyone is as perfect as I am.....
(Please note: Meant as sarcasm :)
