Yes.
...oh, you mean you want me to do so? lol!
Ok, let's get a little more info out of it. =o)
$TEST1 = "030";
@HOLDER = ("020", "040", "034", "056", "030");
@hits = grep /^$TEST1$/, @HOLDER;
$hits = scalar @hits;
You see, grep() returns an array of those elements from it's input list
that match its test condition. This would only give you those elements
of @HOLDER that exactly match $TEST1, and would store them in @hits so
that you would be able to tell how many there were. An array in a
scalar context yields its number of elements, so $hits is how many
there were (which can be none). the "scalar" keyword in this example is
optional, but it's clearer if you add it.
No complicated algorithm required, though there is *ALWAYS* more than
one way to do it, and sometimes others are more efficient.... but
efficiency is not always more important than readability. ;o]
