Re: [MacPerl] Finding array index

[Arved Sandstrom <Arved_37@chebucto.ns.ca>]

You pretty much answered your own question. If you want an index, you use
the 'for' loop (or use 'foreach' and have another variable that gets
incremented on each iteration).

Incidentally, I don't think you want to write a 'for' loop using commas,
as you've shown below. It's worth pointing out, because it's syntactically
OK - it just won't do what you want. What you have is equivalent to

@alist = ($i = 0, $i <= $#array, $i++);
for (@alist) { do stuff }

where the elements of @alist are just 1, 1 and 0. Use semicolons.
