If you use the inverse notation like

print "ok" if $var == 1;

you can use or not use params.

You can do how you like the best.
In this case, because there are no braces involved, you can also skip the params and the code will be more natural 

go_to_school('now') if $you eq 'ready';

Thanks for this, but when doing the one liner, don't we still have to use the brackets? Your example was like this: 
$b = 1 if $a >0;

But do we have to do it like this?
$b = 1 if ($a >0);

Hello Lamar:
As I understand it, PHP works as you say, but in Perl, to do it, you reverse 
the order in the one--liner:

$b = 1 if $a >0;

HTH,

Humberto

I need a little reminder and clarity about "If Else" statements.
I only need to use the braces when there's more than one statement made
based on the condition of the "if" statement, right?

if ($a > 0)
{
$b =1;
$c =2;
}

But, if only one statement is made, I don't need the braces?
if ($a >0)
$b = 1;

With All Respect,
Upshaw, Lamar T
