Yes, Beth was absolutely right about the way to fix my example of a generator that returns variables. I find it interesting that Icon attempts to preserve the "variable"-ness of a returned entity, dereferencing it only if it has to. But I can't think of a way of moving a variable in the other direction: from caller to callee. Not only does Icon have call-by-value---there doesn't seem to be any way to circumvent it. Or is there------? Paul Paul Abrahams abrahams%wayne-mts@um.cc.umich.edu
