Chipp, I use that form all the time ("if it is empty then exit to
top") - I just had a problem regarding dangling THENs..
IF <condition> THEN
<command>
IF <condition> THEN
<command>
Does one execute after the other, or is the second executed only
after the first condition is met? THIS is not clear, so I tend to be
quite explicit or use a CASE statement. Kinda like using parentheses,
might as well give the compiler succinct instructions!
It's a matter of preference I suppose. For me, "if it is empty then
exit to top" is much easier to read than 3 lines taking up the same
space.
Thanks to Eric for Mark Waddingham's explanation. It helps to
understand the why.
