I am wondering if the performance (time efficiency) of hash

my structure needs to hold the members of different groups. I have

Whichever is easiest to read is probably the better solution.
Unless you are dealing with a finished program where you need
additional speed, let readability be your guide.

Hi,
Of course! This is the example of a script with recursive call that produces a
list of the directory paths and filenames of all .htm and .shtm files
contained within the subdirectory assigned to the $base variable.
__BEGIN__
#!/usr/local/bin/perl
$base = /home/users/myspace/html/;
$delim

Hi,
It does:
perl -le'
use warnings; use strict;
sub recursive {
my $cnt=shift;
print recursion level $cnt;
recursive(++$cnt) if $cnt10;
}
recursive(0);
'
That's very clever John,
I'm wondering why ($cnt++) won't work instead of this
recursive(++$cnt) if $cnt10;
I tested it, it gave endless recursion.
And what's the meaning of 0 here?
Why didn't you pass 1 as for recursive(1),
which is more sensible to me? Which also works.
recursive(0);

oh, thanks a lot.
but if you declare prototype of a sub routine, like sub recursive($$), perl
report main::() called too early to check prototype at sample.pl line
XX.
is it important and honw to avoid it?

Yes, spontaneosly I used $cnt++ first, too :-)
++$cnt is called pre increment - in
