I need an equation of the type

\begin{equation*}
    lim_{Z=X-Y,X,Y>0}
\end{equation*}

which results in a long subscript that is ugly. How can I write this so that the superscript has two levels, with Z=X-Y on the top level and X,Y>0 on the bottom level?

Surely a duplicate, but \lim_{\substack{z=x-y\\x,y>0}} will do. It needs \usepackage{amsmath} – egreg Aug 20 '16 at 05:28
@egreg yes, it is a duplicate. Apologies all... – Freakalien Aug 20 '16 at 05:44
