empty is zero

[Mark Schonewille]

Hi Scott,

If you check empty = 0, you'll get false, but if empty*1 = 0 will  
return true. AFAIK it has always been like this. I assume that tParam  
gets parsed when it is passed to a function or command handler. You  
can change the offending line of your script into: "put tParam is zero  
and tParam is not empty"
