( #3333=superdoc: print w/replies, xml ) Need Help??

OP said error only happens on D<, not d<, which doesn't run on my machine.

However, here is a number for which the error occurs on 5.32 with d<

#!/usr/bin/perl -l use strict; use warnings; my $template = 'd<'; my $nv = 2.4; $nv = 4135; # NOTE errors for this number my $p = pack $template, $nv; my $s = "'$p'"; print ">$s<\n"; system $^X, '-wle', "print unpack('H*', $s);";


>''@'< Can't find string terminator "'" anywhere before EOF at -e line 1.

which shows that my guess that the pack produces a single quote character is plausible.

In reply to Re^3: pack() returns an unusable string by tybalt89
in thread pack() returns an unusable string by syphilis

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.
