Something like...
if STRLOWCASE(!VERSION.OS_FAMILY) EQ 'windows' then $
spawn, 'DIR C:\TEMP' $
else $
spawn, 'ls /tmp'

Sverre,
In UNIX, both spawn and call_external work with no problems inside the
VM. To the best of my knowledge there has be no attempt to disable them
like the way execute is disabled so I'd imagine there is no real problem
using them on windows either.
However, it's unlikely that code originally written for UNIX will work
with windows where spawn is concerned. Chances are there were some
assumptions about paths etc. or, worse still, the IDL was spawning a
UNIX command like 'ls' or 'rm'.
Thanks,
Allan

The various fields of the !VERSION system variable will
tell you almost everything you need to know about what
version of IDL you are running. :-)
Cheers,
