Subject: Re: method clear wiping out other array ?

Avdi,
Thanks. I'll look into it. To me they should be two separate objects so 
I would not expect the two names to refer to the same array.

In the meantime a did a work-around.
I created an empty array "dummy" so
arr2=dummy INSTEAD of arr2.clear.
It worked very well - solved the problem.
