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

[Marco Ercolani <m.g.ercolani@bham.ac.uk>]

Dear Statalisters,

I am asking for suggestions on how I can re-program -save9- so that it will work in Stata 13. 
In other words, so it will save data in a Stata 9 format from within Stata 13.
I can think of two possible strategies to achieve this within Stata 13:

Strategy 1: Edit the contents of the dataset so they conform to Stata 9 protocols, save the file,
then edit the the file header so that it appears to have been saved by Stata 9.

Strategy 2: Use an existing save facility in Stata 13 that would allow me to impose limits on the 
data so it respects Stata 9 protocols. Does such a save facility exist?

Any help on the above two approaches or helpful suggestions for a "third way" would be welcome.
