Hi,
Welcome to Perl!
Delaring variables can be done at the beginning of your program/code or at the point where you being to use those variables in the code.
For example,you may declare varaibles at the beginning of your code as in -
#!/usr/bin/perl
use strict;
use warnings;
my $variable1;
my $variable2;
...
...
### Rest of the code follows from below
...
...
### End of the code
Also, if you are declaring variables close to the point where you begin to actually use them, you may do something as below:
#!/usr/bin/perl
use strict;
use warnings;
....
....
...
for (my $variable1=0; $variable1 <= $#someArray; $variable++) {
### Do something here
...
...
}
...
### Rest of the code here
...
Best Regards,

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).

or How to display code and escape characters
are good places to start.
