HELP!!! This is truely doing my head in now.

I have been working with batch files to launch MS Office documents and
presentation files. I have been using the fscommand to launch the batch file
containing start /D "../docs/" one_business.pps. The batch file worked fine on
Microsoft Windows 2000 however on Windows 98 it comes up with the following.

On some machines I get a message come up when Flash comes to launch the batch
file to view the .pps file.
Normally command prompt pops up (very very briefly) before launching the pps
file, however on some machines is comes up with the following:

Drive:\fscommand>start /D "../docs/" one_business.pps
Invalid switch - /D

Drive:\fscommand>
Drive:\fscommand>
Drive:\fscommand>
Drive:\fscommand>

Strange...any ideas? Obviously this combined with Powerpoint 97 and 2000
diffences is a real headache.
Note: Drive ovviously = C,D,E etc depending on set-up.

Please help.

Thanks
