This also works, and doesn't require duplicating parameters passed to print / printf:
use strict; use warnings; my $a = chr(65); my $b = chr(66); my $c = chr(67); printf ('%1$s'x2 . '%2$s'x3 . '%3$s'x4, $a, $b, $c);
The %number$ modifier allows you to use a specific parameter passed to printf (see sprintf for more details), so we create a format string that prints the 1st parameter 2 times, the second parameter 3 times and the 3rd parameter 4 times, or '%1$s%1$s%2$s%2$s%2$s%3$s%3$s%3$s%3$s' though bear in mind if you use an interpolating string ("..." or qq{...}) you would likely need to escape the $ to \$

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

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
