Thanks to all of you who responded to my queries on how to find out the working directory ID for the current default volume. Your tips on using GetWDInfo, and Tech Note 218 were most helpful. Now, I have a related question. Once I have a volume name, a file name, and a working directory ID, I assume from what I have read in Inside Macintosh, that I have a fairly permanent full specification of a file/directory/volume. With these three items, how do I set the default volume/directory to that specified by my volume name and working directory ID, so I can open the file? I don't think I can just use SetVol, as that requires a volume or working directory reference number, which is different from the working directory ID (correct?). I am working under the assumption that both the volume and working directory reference numbers will not be the same after rebooting the machine, but the working directory ID will be. So, when I start an application, I would like to use the volume name and the working directory ID to set the default volume, but I don't know the appropriate toolbox call(s) to do this. I know there is a call by the name of OpenWD, but this seems to require that you know the volume reference number in advance. Any help with this? Please respond by e-mail, and I will summarize to the group. Thanks, Ty A. Lasky lasky@iris.ucdavis.edu

They (Apple tech pubs group) should have you help write the IM. As if you aren't busy enough :-) Thanks for the explanation.
