Stata has a "saveold" command. As long as _new_ versions of gretl can save in
the "old" format, we should be ok. How about
store --oldbinary
?
In its basic form that's doable quite easily. I was slightly
reluctant to propose it because then the issue arises: should this
be supported in the GUI counterpart of "store"? and it's a wee bit
of pain to do that, plus maybe it's more choice than is really
wanted in the GUI context. Nonetheless, maybe it's the Right Thing.
