Many thanks to Roger and Dave for their help.
Roger's advice has been helpful and, most importantly, it worked!

Dear Statalisters:
I guessed the same thing about saveold, but then checked the help menu
of Stata
9 and found
******************************
"saveold saves the dataset currently in memory on disk under the
name
filename in Stata 7 format.
"If you are using Stata 9 and want to save a file so that it may be
read
by someone using Stata 8, simply use the save command. Stata 8 and
Stata
9 share the same dataset format."
******************************
I can't guess the reason for Ilaria's problem (SE to intercooled
perhaps?), but
she should surely be able to get round the problem by following
Professor
Newson's advice.
