Well, for a three-line randomization, this snippet doesn't require a text file to begin with. A

$gettok( ,$r(1,3) , 32 )

should get the job done right. :P

Or:

var %var = $r(1,3)
if (%var == 1) { do this }
elseif (%var == 2) { do that }
else { do another }

But then again, it's considered quit a bit of effort to jot down or copy / paste everything on the body of a text file to be randomized utilizing

$read()
