nested ifs

[Stephen Barncard]

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!
