Odd Empty behavior

[Scott Rossi]

Hi Bill:

Over here, I get "not empty" using both 6.6.0 and 6.6.1.

I was going to mention something about being careful with arrays and
determining empty values, but it looks like the RunRev guys changed how
the engine "sees" the contents of arrays.  A quick test:

In LC 5.5:

put "XX" into theArray["data"]
answer theArray is empty -- RETURNS TRUE

In LC 6 & 7:

put "XX" into theArray["data"]
answer theArray is empty -- RETURNS FALSE
