( #3333=superdoc: print w/replies, xml ) Need Help??
... I also included: use strict; use warnings;

Really?  With use strict it should've stopped working

#!/usr/bin/perl use strict; use warnings; our $pax_1 = "foo"; my $plus = 1; my $name = "pax_$plus"; my $paxing = ${$name}; print "$paxing\n"; __END__ Can't use string ("pax_1") as a SCALAR ref while "strict refs" in use +at ./880063.pl line 8.

unless you also disable strict refs, e.g. as follows

#!/usr/bin/perl use strict; use warnings; our $pax_1 = "foo"; my $plus = 1; my $name = "pax_$plus"; my $paxing; { no strict 'refs'; $paxing = ${$name}; } print "$paxing\n"; # "foo"

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