You'll find that if you don't use spaces around the {}'s, it will affect the code. There may be instances where mIRC will manage to get through without the spaces and get you results, but in general, it will fail. You'll want to always use spaces around the {}'s. The one exception to that is on the EVENT line, where you can have the { touching the final : in the event as seen in the on TEXT event above. And even then, if you want to get in the habit of spaces so you never forget, you may want to just use a space there as well. That's up to you, but it does keep you from accidentally forgetting a space around another {}. Most people don't bother, but if it helps, go for it.
