Confusing Lack of an Error

[deleted_user]

I'm a slightly confused beg/int SAS programmer: I ran the code below--as you can see, it's missing a semicolon after the 'do'. However, I got no error message in my log, the code ran perfectly, and the output is exactly the same as when I ran the program with the semicolon interted. Can anyone enlighten me as to why my mistake didn't hose everything up?

...
else if first_sell < first_buy then do
type = 'seller';
first_date = first_sell_date;
first_class = trim(left(year(first_sell_date)))||'/'||trim(left(month(first_sell_date)));
end;
