Re: Scalars, Lists, and Arrays

in reply to Scalars, Lists, and Arrays

I found Figure 1-1 on page 11 of the Camel book (3rd Ed.) to give a nice visual explanation on arrays and associative arrays. It aslo helps to see the containment of scalar values within such arrays.

Good Hunting,

yet another observation: perl arrays and lists are different in the sense that enclosing a ( ) around a bunch of numbers will concatenate them when used under a comma operator, while when used under a `[ ]` they retain their identity. anything like: my @data = ( @xvalues, @yvalues ) concatenates xvalues and yvalues. if xvalues/yvalues is an array then they get concatenated. however if they are lists `[ ]`, they retain their identity.
