How can I train myself in working with arrays professionally?

Are there any resources for learning about arrays? I want to learn how to take advantage of their efficiency both in speed and simplicity. That will save me a lot of time when I use arrays manipulation instead of using FOR loops as they are much much faster and efficient.

Thanks, Ahmad

I am afraid you are a little misinformed. Working with arrays, commonly known as using vectorized code, is not necessarily faster than using FOR loops - often it is slower and more memory intensive. All you have to do is look at some of the posts on this site to find this to be true. For a recent example, look here (there are many many more examples to be found):

Having said that, you can learn how to use vectorized code by also looking at posts on this site, and over on the newsgroup. Writing good code is often a matter of knowing what approach to use in a given circumstance, and according to requirements/resources, and that comes from experience.
