Just saying, the min() function will do what's wanted here, for 2 or
more series, at the cost of defining a list, as in
<hansl>
open data4-10
series mymin = min(deflist(ENROLL, CATHOL))
</hansl>
Aaaah, very clever, I hadn't thought of that. That said, I still think
xmin(a,b) would probably be a more straightforward solution for the
average user. Any objection to my patch?
