Picking up on Nick's comment, the dirsep is shorthand for directory
separator, so it will return a valid directory separator depending on the
operating system.

you might be able to attack you problem by code like this:

early in you do file, define the drive:

local drive=cond("$S_OS"=="Windows","C:",":C")

..then later code:

use `drive'`c(dirsep)'stata`c(dirsep)'auto, clear


This should work on both mac and windows...
