I agree with what the previous monks have said. I use it for tools and being a dba/admin, I have many tools where it is very useful for generating output. For ex:

sub print_logcon {
    my ($which,$f1,$f2,$f3,$f4) = @_;
    if ($which eq 'general') {
        print "$f1";
        print LOG_FILE "$f1" or kill_and_clean_up( "Error printing to 
+$LOG_FILE: $!" );
    }
    elsif ($which eq 'comparison') {
        my $f1_multi = $f1;
format COMP_TOP =

                     File version comparison

Type File name                            Previous           New
----------------------------------------------------------------------

.
format COMP =
@<<<< ^<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< @<<<<<<<<<<<<<<<<  @<<<<<<<<
+<<<<<<<<
$f4,  $f1,                                $f2,               $f3
~~    ^<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
      $f1
.
    select(LOG_FILE);
    $^ = 'COMP_TOP';
    $~ = 'COMP';
    write LOG_FILE or kill_and_clean_up( "Error printing to $LOG_FILE:
+ $!" );
    $f1 = $f1_multi;  # format destroys the variable, so reassign it
    select(STDOUT);
    $^ = 'COMP_TOP';
    $~ = 'COMP';
    write STDOUT;
    }
    elsif ($which eq 'file_info') {
        my $f2_multi = $f2;
format FILE_INFO_TOP =

                     File Compilation Information

Type        File name                                         Version
----------------------------------------------------------------------

.
format FILE_INFO =
@<<<<<<<<<< ^<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<  @<<<<<<<
+<<<<<<<<<
$f1,      $f2,                                            $f3
~~          ^<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
            $f2
.

    select(LOG_FILE);
    $^ = 'FILE_INFO_TOP';
    $~ = 'FILE_INFO';
    write LOG_FILE or kill_and_clean_up( "Error printing to $LOG_FILE:
+ $!" );
    $f2 = $f2_multi; # format destroys the variable, so reassign it
    select(STDOUT);
    $^ = 'FILE_INFO_TOP';
    $~ = 'FILE_INFO';
    write STDOUT;
    }

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