Agreed, and I had completely misread Ben's problem.  Also, the code I
offered had a missing index

The difference between this and "gen y = x[z]" is that rankx does not
point to the element in x to be copied, but to the position in y where it
is to go.

* gen y[rankx] = x

is the code that is disallowed - but by the time you read this it may be
in the latest upgrade.
