( #3333=superdoc: print w/replies, xml ) Need Help??
Thanks for all the quick responses. I'll be sure to vote up a bunch of posts. I ventured over to the other thread and found this code. I don't really understand what is occurring, so I thought I could explain it to the best of my abilities, and you guys could help by filling in the gaps?

#! perl -slw use strict; my @a = 1..3; my @b = 'a'..'f'; my @c = map chr, 33 .. 37; nFor( 3, \@a, \@b, \@c ); #3 sets the number of arrays to sift through +. sub nFor { my $n = shift; #I understand shift chops off the first element in +an array, but what purpose does that serve? Also, how are the arrays + (@a, @b, @c) referenced in this code? if( $n ) { #what exactly is $n? for my $i ( @{ shift() } ) { # I have no idea how $i get's it' +s value? nFor( $n-1, @_, $i ); #why does the top nFor call for 4 va +riables, while this one only calls for 3? } } else { print join ' ', @_; } }
I love it when a program comes together - jdhannibal

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.
