Hi there I'm attempting to write a perl script that opens a directory from the command line, opens each file at a time and then according to the information extracted from each line in the text file, stores how many times a set of numbers within a particular 'range' occurs in the text.
So, for example, if I want to count how many times x occurs with a value between 180-175 occurs when y = any value between 170-165, I want to store this information in a array identifying this value range and then print off the total number of times the desired x,y range occurs at the end. Here is a snippet of my code thus far: 

$underscore = "_";

for($i = -180; $i < 181; $i = $i+5)
{
    $j = $i+5;
    
    if(($x >= -180) && ($x < -175) && ($y >= $i) && ($y < $i+5 ))

    {

    $k++;

        $x1 = "substr($i, 1, 3)";
        $x2 = "substr($i, 1, 3)";
        $y1 = substr($i, 1, 3);
        $y2= substr($j, 1, 3);

    # attempting to name array according to value range

        $array = "array$underscore$x1$underscore$x2$underscore$y1$unde
+rscore$y2";

        $count = $count +1;

        $array[$k] = ($count);

        print "$array[$k]";

This doesnt seem to work at all as I am unable to get the array value to print out. Eleswhere, the array wont print out when I use print @array either. I can only assume I'm not naming it correctly or something. Any help would be much appreciated
