Like this
print for map{ join '|', map sprintf( "%02d", $_ ), $_*8+1 .. $_*8+8 }
+ 0 .. 7;;
01|02|03|04|05|06|07|08
09|10|11|12|13|14|15|16
17|18|19|20|21|22|23|24
25|26|27|28|29|30|31|32
33|34|35|36|37|38|39|40
41|42|43|44|45|46|47|48
49|50|51|52|53|54|55|56
57|58|59|60|61|62|63|64
Or perhaps this comes closer to your "one loop" ideal?: print for unpack '(A24)*', join'|','01' .. '64', '';;
01|02|03|04|05|06|07|08|
09|10|11|12|13|14|15|16|
17|18|19|20|21|22|23|24|
25|26|27|28|29|30|31|32|
33|34|35|36|37|38|39|40|
41|42|43|44|45|46|47|48|
49|50|51|52|53|54|55|56|
57|58|59|60|61|62|63|64|
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

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).
