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 ...

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
