hi,
i came across this statement while reading Perlop. I don't understand how %s
is substituted w/ "s" or w/o "s" depending on the no. of dogs. %s is a hash.
how is it associated w/ the ?: operator?
it prints " i have 0 dogs." but if i change 1 to 0, it prints "i have 0
dog."
grateful for your ti
thanks for all the people who answered

hi perl friends,
i have a @list that contains elements i do not know. i'm using grep to match
some words inside the @list.

$match = grep /\d/, @list;
my question is: is there a way to find the element No. eg: $list[number] of
the
latest match?
thanks!

hi,
when you want to get rid of newlines and carriage returns, is it correct to
use:
tr/\n&&\r//g; ?
below you suggested tr/\x0a\x0d//d;
what does "x0a" and "x0d" mean?
where can i get a list of all these strange characters and their meaning?
a few days ago, Bill suggested : tr/015d//g; to get
dennis, thanks for the help ! i can't remember
if i thanked you before.
