This is a fine moment for
perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'

;-)

See our. Variables declared with our aren't global.

The only global variables in perl are the 'special' variables, e.g. $_. But with these, "global" means only that the symbol is available everywhere, without any previous declaration - but the actual value accessible through that symbol is subject to localizing and aliasing.

The documentation for our stresses within the current scope - and a block boundary is a scoping boundary.

Say use vars qw($text) to have a package global, or use ${^_text} to have a really real global (the symbol is bound to the package main, though).

--shmem

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

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