tr does not interpolate.

Win8 Strawberry (64) Fri 09/25/2020 23:09:19 C:\@Work\Perl\monks >perl my $kards = -99; my $bad='$card$card'; my $card='K'; eval {print "eval is testing for $card in $bad \n"; $kards = $bad =~ tr/$card//; # tried also tr/$card/$card/; same + bad result. }; print "1: Num of $card in $bad = $kards \n"; $king = $bad =~ tr/$card//; print "2: Num of K in $bad is = $king \n"; __END__ eval is testing for K in $card$card 1: Num of K in $card$card = 10 2: Num of K in $card$card is = 10
Here, tr is counting the number of characters in the '$cards' literal character set that are in the $bad string.

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.
