Stata Reference Manual says that in r(rho) alpha 'saves the average
interitem correlation if std is specified'. I think my original problem was
that I hadn't specified std aftter alpha in the ado file. However, I still
get the same error message about versions even when I use your suggested
code. Thanks for your help,
Patrick

As you know, Stata has a rather
elaborate system of version control designed
to maximise the extent to which old programs
can work with newer versions of Stata,
which does very occasionally not do what
users hope.
However, although you are getting a message about
versions, it could just be a side-effect
of another mistake in your program. Guessing
that -avcorwithin2- here is just a modification
of -avcorwithin- mentioned in your previous
post, I see an error there: -alpha- does
not leave behind any result in r(rho).
You might be better off with something more
this:
program avcorwithin, rclass
version 8.0
tempname y
alpha bef*
scalar `y' = r(alpha)
alpha aft*
return scalar diff = r(alpha) - `y'
end
bootstrap "avcorwithin" r(diff), reps(1000)
