The new command line switches for PowerPoint Viewer 2003 are:

/L -- Read a playlist of files contained within a text file.

Example: \pptview.exe /L "Playlist.txt"

/S -- Start without splash screen.

/P -- Print the presentation.

Example: \pptview.exe /P "Presentation.ppt"

/D -- Prompt the Open dialog box to appear when slide show ends.

/N# -- Open presentation at a specified slide number "#".

Example: /pptview.exe /n5 "presentation.ppt" would open at slide 5.

The playlist file itself is simply a list of presentation filenames
(preceded by path as needed) and does not support any addition command line
switches to be applied to individual presentations within the playlist.

So the functionality that is lost included:

* No more loop continuously switch. Each presentation will loop or not loop
depending on how it was saved by the author (set up show dialog) this
includes not being able to loop/repeat the contents of a playlist (the
contents of a playlist are show just once).

* No Kiosk password dialog switch. Viewer will display presentations in
kiosk mode if specified by presentation author (set up show dialog) but you
cannot specify a kiosk slide show password that prevents stopping of show
without entering a password.

* Cannot specify a slide range to show. Viewer will display the range of
slides specified by the author (set up show dialog).

* Cannot force automatic advancing of slides. Viewer will automatically
advance slides if timings and slide show settings have been specified
appropriately by the author (set up show dialog)

* Virus protection warnings cannot be enabled/disabled by choice.
