RE: howto: array index inside a foreach loop
yeah sorry, my problem is not quite as simple as the example. I just put
that in to try and illustrate my point. I'm not trying to do a straight
replace, I need to replace an element only if I find a certain string
somewhere else.

sorry i might be missing your point but why not just:
#!/usr/bin/perl -w
use strict;
my @array_of_strings = qw(CRASH Windoes use linux);
s/^CRASH/LOOK OUT!/ for(@array_of_strings);
print join("\n",@array_of_strings),"\n";
__END__
prints:
LOOK OUT!

Re: howto: array index inside a foreach loop
You need to use a for loop for this.

howto: array index inside a foreach loop
Say I have a foreach loop that I used to modify elements when they match a
pattern that I am searching for, but there is one special case where I get a
match and I need the index for that element. Can I get that index or do I
have to go with a for() loop. If this can be done how would I use it?
Thanks in advance
Ken
# something along these lines
foreach $temp_string (@array_of_strings)
{
if ($temp_string =~ /^CRASH/)
{
$array_of_strings[$this_is_what_I_need - 1] = "LOOK OUT!";
}
}
