This is not a bug - it is a feature that has been available for over 20
years that I know about.
A<-1> = B does not change A if B is blank. Means there are no blank items
in A. Useful!

Reviving an old thread.
I was emailing a friend about this and he came up with a unique suggestion
that is a direct replacement for the <-1> but actually works as desired.
And I've wiped out the original post, so I'm not sure who originated it.
But if you're still out there and still looking for an easier route, this
may do it for you.
I got bit by the <-1> bug today in mvBase and already had it changed to a
direct assignment when Trey sent this to me. So if you're using mvBase,
beware the <-1> 'bug' lives there as well. fwiw...

I always use A.VAR := @AM[1,NOT(NOT(A.VAR))]:NEW.DATA
It is much more reliable and much quicker than <-1>

Oh yeah, sure. I agree. Using LOCATE or FOR/NEXT is my preferred method,
but the <-1> does come in handy in some cases, and actually was the main
point of the original posting (see bottom in case you weren't following
this
thread)

If you want them to stay in sync, keep a pointer variable and update
each multivalue in tandem using the variable (which points to the mv
position) rather than use -1. Personally, I think -1 is fine if
there's only one array; if there are multiple to keep in tandem -1 is
a yellow flag, fraught with all sorts of impending data corruption.

Previously, code of A<1,-1> = B, when B was blank made no change to
A.
