agreed. Thanks again, Jeff.
In trying to keep it simple,

Do not use a regular expression to check for equality. It breaks far too
often.
* the $ anchor does not match the end of the string -- it matches the
end of a string OR before a newline at the end of a string
* if $TEST1 has any
And I thought you were a raw newbie. lol!
Sorry. Just trying to be explicit. ;o]

Yes.

I've answered my own question:
my $ID = "020";
my $rh1 = {id => 1, value => "020", name => "one"};
my $rh2 = {id => 2, value => "040", name => "two"};
my $rh3 = {id => 3, value => "034", name => "three"};
my $rh4 = {id => 4, value => "056", name => "four"};
my $rh5 = {id => 5, value => "030", na
I haven't really played with grep at all, except for doing the standard
stuff on dirs.
Your example is wonderfully concise -- is there any way that you can expand
on this to get more information out of the test, ie which member of the
array matches, or returning the member if this were in a fu

You can do it a couple of ways (there's ALWAYS more than one way to
1, '056', 1, '030', 1);
if ( defined $Holder{$TEST1} ) {
# found, so do something
}else {
# not found do something
}

lol -- welcome aboard, and don't worry about it.
Just be sure to do this:
perldoc -t perl >tmp
and then look at tmp to see the things you can look at in more
Perl has a foreach loop that is very apt at doing what you want.
i.e.
#!/usr/local/bin/perl5
$test1 = "030";
@holder = qw(020 040 034 056 030);
foreach (@holder) {
$test = true if ($_ == $test1);
}
This loop cycles through each element of the array, temporarily housing it
in the special
Hi,
Today is my first day on Perl so please bear with me if this sounds
stupid...
How can I find out if an array contains a particular element stored in a
certain variable ?
eg variable TEST1 = "030"
array HOLDER = "020 040 034 056 030"
I need to find out if "030" is present in the array HO
12 matches
