Okay I screwed that example up... Last line should say:

while (my($n,$v) = each %input) { print "$n: $v<br>"; }

It won't work the way I have it for 2 reasons: 1. I kinda threw a semi-colon in between the EXPR and the loop 2. You must show the loop first when initializing variables within the loop statement (in order to satisfy strict).

And okay, so the following code would work:

#!c:/perl/bin/perl -w use strict; use CGI 'Vars'; my %input = CGI::Vars; print "Content-type: text/html\n\n"; while (my($n,$v) = each %input) { print "$n: $v<br>"; }

Let's go to lala land and pretend could not do this. What would be the best alternative? (By the way, thanks. I have already modified my scripts to use this wonderful CGI::Vars ;))

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.
