[Columbus-pm] perl question

[Terrence Brannon]

Hi Mark, I figured someone would've answered by now who still lives in
Columbus, but I guess not.

Your question about getting the first statement to work... I presume the
'first statement' is
        sort rv @list;

And presumably you have some form of this statement that works with
parentheses? My solution would be:
      sort { $a <=> $b } (rv @list);

But your best option is the 'Seekers of Perl Wisdom' section on
perlmonks.org ... or perhaps ask on stackoverflow.com

Good luck and regards from South Florida,
Terrence (on my way to freeze and do Python in NYC)
