tr/// can be used to count characters in a string. No need to loop through.

use warnings; use strict; print "LATCG-\n"; while(<DATA>) { print $. . tr/A// . tr/T// . tr/C// . tr/G// . tr/-// . "\n"; } __DATA__ ATGAAAAAGAC AGCTATCGCGA TTGCAGTGGCA CTGGCTGGTTT CGCTACCGTAG CGC-A---TAG

Output:

LATCG- 171120 232330 323240 405240 522430 621224

Title:
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!
  • 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
  • Outside of code tags, you may need to use entities for some characters:
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
