[amibroker] converse of NZ() function?

["dchang813" <dchang813@xxxxxxxxx>]

Hi--

I'm looking for the converse of the NZ() function--in other words, I'd
like to turn all zeroes in an array to Null.

For instance, given an array of:

1 0 0 1 1 0 1

I'd like to turn it into:

1 Null Null 1 1 Null 1

Why?  I'd like to be able to create a "mask" array that can be used to
cut holes in an otherwise continuous indicator.

So, say the indicator's array is:

33.54 33.51 33.50 33.53 33.49 33.40 33.30

Doing a bitwise & on this array and the mask I gave above would produce:

33.54 Null Null 33.53 33.49 Null 33.30

The plot would then show line segments connecting these points (or so
I hope).

Can this be done without looping through the mask array to replace the
zeros with Nulls?

Thanks,
Dennis.
