interface to win job scheduler portable from win98 .. winXP / cmdline or COM ?

[Robert]

I found the os.popen("AT /?") way ....
however it works not on Win98 and the "Day" you enter at the AT are language
dependent.  (e.g. Mi(ttwoch) in german, We(dnesday) in english Windows
versions)

I need a solution work from Win98..WinXP most independent from
internationalization etc.

is there portable way - or at all a way to manipulate the Win98/ME scheduler
?
if no simple means, even COM stuff would be ok.
any pointers?
