Dear Monks,
I have implemented a short sample code of question for better explanation.
I am trying to use a string storing an integer that I want to increment when ever I would be calling my sub program.
My solution so far is storing the value on a .txt file reading the value and icrementing it on every round. Sample of working code is provided under.
I am wondering if there is a possible solution, to store the value to an allocated memory, that will be not used until I calle it again. I want my subprogram to be able to complete the process and not loose the value from the memory. I was even thinking in worst case scenario to use MySQL database but I want to avoid this solution.
#!/usr/bin/perl
use strict;
use warnings;
my @words;
my $word;
my $text;
my $file = "test.txt";
open (DATA, "+<", $file)
or die("Could not open file: ".$file.". $!\n");
sub add {
print "I am in\n";
while( <DATA> ) {
chomp;
@words = split('');
foreach $word (@words) {
print "This is word: ".$word."\n";
$text = $word + 1;
print "This is the new word: ".$text."\n";
}
}
}
&add();
print DATA "".$text."\n";
close (DATA);
Thank you for your time and effort.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
