I mean this: (arrays can have logical values assigned - an array of logical values)
LOCAL aArray[1]
?VARTYPE(aArray[1]),aArray[1]	&& "L" and .f.
aArray[1]=.F.
?VARTYPE(aArray[1]),aArray[1]	&& "L" and .f.


Oh, I suppose you could assign 0 for false and 1 for true but my point is than there is a built in ambiguity about empty arrays.
