Re: does foreach choose in order?

[Brent Michalski]

Yes, for and foreach will select the elements of the array starting at 0
and ending at the last element.

It is the %hash that you are thinking of that does not read data in the
order in which they were put into it...

HTH,
Brent

I need to read elements from @blah from "left-to-right" (ie. in the order
that successive shifts would read them).  I seem to remember reading
somewhere that one should use 'for' only when s/he doesn't care about the
order in which the elements are chosen.  However, every time i try 'for
(@blah)', it reads "left-to-right".

In other words, is
           for (@blah)
           {
                     whatever($_);
           }
effectively equivalent to
           for ($i=0;$i<@blah;$i++)
           {
                     whatever($blah[$i]);
           }
?
