In Perl 5 the only difference between the '=' and ',' operators is
that the '=' operator treats the word on the left like a string.
The '=' is preferred when working with hashes because it provides a
visual cue that you are not dealing with a normal list.
I'm unable to arrange the numbers in an array in ascending order.. I
tried the following
@asc = sort{$a=$b} @list;
but it didnt work. I did a subroutine
sub con{
my ($a,$b);
$a=$b;}
Then i tried
@asc = sort con @list; #didnt work
Can anyone please help?

What's your array's content?
It do can work using Perl's sort (see below),also please see 'perldoc -f sort'.

It works for me. What are you doing differently? Can you reduce your
problem to a small test case that you can post?

What are you trying to achieve Jeff? Are you concerned that someone may write
malicious code that calls package functions that are meant to be private? Or
are you more interested in avoiding coding mistakes caused by calling the
wrong function?
In fact nothing at all.I'm also using Perl's OO
Hi Jeff Ji, your program worked. But i couldn't understand the second
line.. That long print statement. What happened there? My 'simple'
sort arranged numbers in dictionary style.. Like 0 then 1 then 17 then
2 and then 29.. And how come in using strict module, that $a and $b
didnt make any noise?

IMO it's useful, otherwise it would not be widely used, and for example,
Test::Pod::Coverage would require subroutines starting with an underscore to
be documented. :-)
