Thanks for the reference Nick. It does look like the same problem. I was
surprised to think that I was the first one to come across this and was
thinking I might have a candidate for my first public .ado contribution
(after considerable revision to make it more general). Pity.

Subject: RE: st: forvalues and _N
This looks like the problem tackled already by
Roger Newson's -sencode- (SSC) and my -oencode-
(private domain). Last time I looked, Roger's
could do things mine couldn't do, and versa vice,
so I guess I should make mine public too.
