[Jprogramming] How to tell if all boxes in a row are empty?

[PR PackRat]

I need to perform a certain action if an entire row in a transposed
table (i.e., originally a column) has empty values, that is, all boxed
data are the equivalent of a: or ''.  The result should be a Boolean
value--"true" meaning that the entire row has empty values.  (A
typical application would be old stock market data, where all of the
"Open" values might be null or empty.)

I don't know how to even begin writing such code (without a for/next
loop to separately evaluate each box's value, a very non-J way of
doing it).  Please help.  Thanks in advance!
