I would like to be able to open a text file that resides on an appleshare server. If the file is already open by other users, HyperCard will alert me with a dialog box. I would like to be able to open the file from a script and be able to check if an error occurred (like any normal open command). Is there anyway to achieve it through HyperCard (I believe that the answer to this one is - no) Is there an XCMD that opens a file in a graceful way ? If not, is there an XCMD that checks if a file is already open?

An XCMD could be written (very few lines of C or Pascal) that would open a file. Such an XCMD would need to call FSOpen or PBOpen or Open (all variations on a common theme). All of these calls return a status result. If non-zero, then an error (such as the file already being open read/write) is returned. Such functionality is NOT build in to HyperCard.
