Re: st: How to re-program -save9- for Stata 13? |

As I understand it, Strategy 2 is doomed in a strict sense. -saveold- will not take you that far back and there is no -saveveryold- or equivalent that you want. Strategy 1 is to a degree programmable, but you need a really good understanding of Stata and Mata programming. In generality, you have to decide what to do with long strings, etc., etc. and to document that. Pessimistically, Stata 13 datasets will _not_ all fit in Stata 9 and there's no fudging that fact. But what's the context here? One might guess that locally some people have access to Stata 13 and some just Stata 9, so you want to heave datasets back and forth, and 9 to 13 is easy and 13 to 9 the problem. I guess I would just start with something like -outsheet- or -export excel- as intermediary as something a lot simpler than writing a new program. Also, what's so magic about 9 as compared with anything else not reachable by -saveold-? For completeness I have to add that -save9- was discussed in earlier postings on the list by Joerg Luedicke and myself. http://www.stata.com/statalist/archive/2011-04/msg00654.html http://www.stata.com/statalist/archive/2011-10/msg00928.html http://www.stata.com/statalist/archive/2011-10/msg01158.html http://www.stata.com/statalist/archive/2011-10/msg01253.html At that time I was left puzzled about the claims on its behalf, and I guess that would still be true. I think Joerg felt the same.
