Re: st: Stata 9 announcement
Richard Williams (Richard.A.Williams.firstname.lastname@example.org) asked about the
data file formats of Stata 8 and Stata 9:

The file formats of Stata 8 and Stata 9 are identical, with one
caveat. In Stata 8, value labels had a maximum length of 244
characters (Stata/SE) or 80 characters (Intercooled Stata).
In Stata 9, value labels have a maximum length of 32,000
characters. When reading a Stata 9 dataset, Stata 8 is
"smart" enough to not read in any value labels that would
exceed the Stata 8 limit.
The -saveold- command in Stata 9 (as in Stata 8) will save
the current dataset in Stata 7 format.
