UBB.Developers Forums Community Development Programming PHP and Server-side Scripting What does this mean?

Ok I was reading Perl by Example, when I came over this NOTE:
If the right side of the range operator is greater than the left side, an emptry array is created.
Should an emptry array be created if the left side of the range operator is greater than the right side?

I need to see the exact piece of code with the discription in order to give you a contextual answer.

There is no code to that, It's in Chapter 4 of Perl by Example, and he's just giving a special note to everyone about using the Range Operator.....

Sounds like that is reversed (the descritpion)

if you did

@blah = (1..20);
print @blah;

you would get the numbers from 1 to 20 in the array.

if you did

@blah = (20..1);
print @blah;

you would get nothing.

Yeah that's what I thought, thanks for the description Mark.
