Thanks much for the reply. There is much to learn...
Anyway, I'd imagine that there is little difference in overhead between
using -sum- in this way and creating and then dropping a temporary variable.
I should get over the frugality issues.

su p_pred_mort, meanonly

su p_act_mort, meanonly
scalar maxmax = max(maxpred,r(max))
di maxmax
See -help return- for more or type -return list- and -eret li- after all of
your favorite commands to see what is available. Also try -cret li-
sometime.
