Re: foreach and arrays

To answer this, execute this block of code to see what happens:

@myArray = (0,0,0,0,0);
$myCounter = 1;

foreach $item (@myArray)
{
   $item = $myCounter;
   $myCounter++;
}
for ( $i = 0; $i < 5; $i++ )
{
   print "$myArray[$i],";
}

You should get the output "1,2,3,4,5,". This would indicate that the foreach operator work sequentially, as one would expect.

Just a pointer, in the time it takes you to type `@myArray` or `$myCounter`, you could just as easily type `my @array` or `my $counter` You do enjoy the benifits of lexically binded variables, don't you? Also, you can save some typing with: `my @array = qw(0 0 0 0 0); # well, not much on this one, but . . . my @array = (0)x5; # pure evil` [download] and use Perl for loops like Perl, not like C! `for (0..$#array) { print $array[$_],','; }` [download] jeff R-R-R--R-R-R--R-R-R--R-R-R--R-R-R-- L-L--L-L--L-L--L-L--L-L--L-L--L-L--	[reply] [d/l] [select]
