If you want to look something up in a book, you'll probably use the index. And so it is in Lua that if you want to look something up in a table (the collection structure in Lua), you'll use an index too.

We have just announced our Public Lua Course - it's a natural for us, as we specialise in niche, open source languages that we like using ourselves - and I thought what better way to tell you about all the various things we cover on the course that an index ... so I'm reproducing (below) the index from our training manual of some 128 pages.

What else do you need to know about the course?

• It runs at our Melksham, Wiltshire, England training centre
• It's a 3 day course starting on 29th Septmeber and again on 17th December
• It costs £850.00 + VAT for the first delegate and £750.00 for the second and subsequent delegates on the same course / order.
• We limit the class size to just 8 delegates
• If you don't live nearby, we're a hotel too and we can arrange for you to be picked up from a local railway station or airport if you come in by public transport - no need for a car.
• Some prior programming experience is required, but if Lua will be your first language please ask as we can usually arrange an extra "lead in" day immediately prior to the course.
• We also run private courses - at our place or yours; such courses can be tailored to suit your exact needs and are lower cost than public course places if you have more than a handful of delegates.
