The other day, while visiting the new Editions de l’OcÃ©an Indien bookstore (appropriately called The Bookstore) in Rose-Hill, I discovered its basement containing lots of old books at very cheap prices.
I bought 5-6 books at Rs. 10 each among which Logo for Beginners by J.W. Penfold.
To be frank, I did not have a very positive opinion of Logo prior to reading that book. It’s only when I came across page 3 that I realized that Logo was something special:
“LOGO derives from a family of languages known as ‘list processing’ languages, and these are the languages of so-called artificial intelligence”
Programming in Logo
Logo, when used to teach programming, is very straightforward. For instance, this is the body of a procedure, called square, which draws a square:
repeat 4 [forward 100 right 90]
The following code then draws the figure that you can see above:
repeat 72 [square right 5]
It’s not complicated and, arguably, can really teach the basic concepts of computation very easily. No wonder lots of schools (especially in the UK) still use Logo.
Where to get Logo?
There are many free implementations of Logo. The “standard” seems to be UCBLogo also known as Berkeley Logo which works on lots of different platforms (Linux and Windows for example). I did not use that one.
Try Logo. I think you’ll be impressed. And, in case you come across that Rs. 10 book, buy it. Rs. 10 is so little to pay to access such a wonderful world…
