gen d = max(a, b, c)

Consider these three columns, a, b, c:


a    b    c    | d
------------------

1    .    .    | 1

.    .    5    | 5

.   0.2   .    | 0.2

2    .    .    | 2


where "." mean no data. Each line has only a box different
from "."? Starting from the first three columns, I would
like to form a new column "d", as in the example above.
