Well there ya go. I should actually read the "What New in IDL X.X" documents.....

Function PATH_SEP in the standard library returns the appropriate path
delimiter for the current platform.
Only since 5.5 though.

I use an altogether different method to accomplish the same thing,
which never requires any specific knowledge about the path delimiters,
etc.:
source=(routine_info('irs_calib_dir_marker',/SOURCE)).PATH
dir=strmid(source,0,strpos(source,path_sep(),/REVERSE_SEARCH ))
where the procedure `irs_calib_dir_marker' exists in the directory I'm
after. You can either use an empty marker procedure, or an actual
procedure. The advantage of this method is that your run-time
required data or directory will be found with the associated routine
independent of how IDL was started, and even if the user has severely
butchered the file structure of your distribution (moving various
directories around, say).
You can also create directories or files relative to this in a
platform-independent way using, e.g.:
file=filepath(ROOT_DIR=cdir,SUBDIR='my_data',file)

Wot about summat like:
CASE STRUPCASE( !VERSION.OS_FAMILY ) OF
'WINDOWS': DirSeparator = '\'
'MAC': DirSeparator = whatever the Mac directory separator is
ELSE DirSeparator = '/' ; Default to Unix
ENDCASE
CD_Dir = '..'+DirSeparator+'source'
CD, CD_Dir, current=currdir
??
paulv
p.s. I didn't check the syntax. And !VERSION.OS_FAMILY might not be the value you need,
but you get the idea.

Just replace '/' with '\'.
