This is very C'ish. In Perl we tend to:
for ( 1..5 ) {
print $_ . "\n";
# sleep( 1 );
}
Uncomment the sleep() thing if you want Perl to sleep for 1 se

In Perl that is usually written as:

Or even easier:
for(1..5) { print; }
Or if you nee the newline:
for(1..5) { print "$_\n"; }

If we're competing, then there's
print for 1..5

I have a list of email addresses in a text file one to a line. How would I
seach for a particular email address?
$email = "[EMAIL PROTECTED]";
while {
if ($email eq $_) {
$OK = 1;
}
}
It seems the @ symbol somehow doesn't work in this search. What would be a
better (or right) way t

You need to escape the '@' in your variable:
/***
open(FILE, "
$email = "[EMAIL PROTECTED]";
while () {
print;
print if (/$email/);
# $OK = 1 if /$email/;
}
*/

I think I figured it out! A FIRST!!
for ($i = 1; $i <= 5; $i++){
sleep 1;
print "$i\n";
}
I prints out like this: 1...2...3...4...5
YES!!

As you move into larger programs and scripts it
is a good idea to always use strict and warnings.
use strict;
use warnings;
