It shouldn't make a difference. Both forms are valid numlists.
. numlist "0/-9"
. ret li
macros:
r(numlist) : "0 -1 -2 -3 -4 -5 -6 -7 -8 -9"
. numlist "-9/0"
. ret li
macros:
r(numlist) : "-9 -8 -7 -6 -5 -4 -3 -2 -1 0"
Notice that whenever you have issued the first command, the second
command is redundant and won't undo recoding of zeros to missing.
