Dear all,
I've a function which searches a given number from an array and returns the result.

Function:

1.    sub checkNumber($)
2.    {
3.            my ($l_number) =  @_;
4.            my $l_status;<br>
5.            my @matches= grep { /$l_number/ } @numbers;
6.            if  (@matches) {
7.                    $l_status="TRUE";
8.            }
9.            else {
10.                    $l_status="FALSE";
11.            }
12.            return $l_status;
13.    }

The Way I call it:

1.    $check=checkNumber($num1);

The array has at least 20K elements. This piece of code is taking up almost 100% of the CUP cycles (Dual Xeon). Would somebody please suggest some alternative solution.

Thanks in Advance
