Question: New info on the label=

New info on the "label=" question. I open a new work sheet and enter solve({x^2-y^2=y,2*x*y*=x}). The answer returned includes RootOf(_Z^2-3, label=_L2). Then I copy and paste that solve command after the next prompt and solve the same exact problem again. This time I get the same exact answers EXCEPT that the label is now _L5 and if I solve the same exact problem a third time I get a third label. I can only conclude that the label has nothing to do with the solutions to the problem. This makes me wonder what then is the purpose of a label? Why is it returned? What significance should one attach to it? I don't want to get bogged down about what the spec says or whether this is a bug. I just want to understand what significance the label is so that I can safely ignore it or understand why I should not ignore it. Sorry that I keep beating this issue but surely there are others that don't understand what a label is for either. Thanks a bunch for being understanding. P.S. I e-mailed Maple about this issue but obviously they don't know either because that was a week ago and still no reply.
