Maarten, Phil thanks for the input so far. Phil your suggested code makes perfect sense to me but still doesn't seem to quite do the job; I want it to clear the current data set and use the `tempresults' data set instead.

If you -preserve- within a do-file (or program), Stata will automatically -restore- at the end of the do-file unless you specifically tell it not to.

Try something like this:

/*===begin===*/
local arg "yes"

preserve
tempfile tempresults
	gen X = 1
save "`tempresults'"

if "`arg'" == "no" {
	restore, preserve
}
else {
	restore, not
	use `tempresults', clear
}
/*===end===*/
