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

That is not very efficient code. Here's my stab at your approach:

use 5.14.2; use warnings; $| = 1; print "Range bottom > "; chomp (my $from = <STDIN>); print "Range top > "; chomp (my $to = <STDIN>); $from =~ m/^\s*(-?\d+)\s*$/ or die "Invalid range"; $from = +$1; $to =~ m/^\s*(-?\d+)\s*$/ or die "Invalid range"; $to = +$1; $from <= $to or die "Invalid range"; my $range_length = $to - $from + 1; my @points = map { $from + int rand $range_length } 1 .. 100; say "@points";

(do you see how many useful comments you get when you show effort?)

Enjoy, Have FUN! H.Merijn

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.
