This should be "eq" for reasons explained below.

== compares numbers. eq compares strings. $a eq $b implies $a == $b, but
not vice versa.

A few examples: "Apples"   == "Oranges"
                "War"      == "Peace"
                "Freedom"  == "Slavery"
                "Ignorance"== "Strength"

I think you get the point.

Yes, but it falsely evaluates to true.

Your main problem is that you're using @currentline[x] to denote array
elements. The type specifying character is always what you *want*, not what
you have, so you must write $currentline[x].
