more intuitive to use the xmin() function, as in "series m = xmin(x,

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?
Haven't looked at your patch (does it handle NAs as wanted?), but let me
put the xmax/xmin functions in perspective: I tend to find them a bit
awkward, allowing only _exactly_ two comparison arguments. Every time I
use them they feel a bit clunky. I believe their existence predates the
generalization of max and min to matrix arguments.
Actually, I formulated my thoughts already 8 years ago, so let me just
link to them:

(BTW, the fact mentioned there is still true that the help text for
max/min does not mention the fact that you can give a matrix as
arguments. This is not a criticism against anybody, because I could have
done it myself, but maybe yet again an argument for creating even more
tickets...)
