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.
