I have a HyperCard stack I'm creating as an entry for a contest, which makes intensive use of sampled sounds. I would like to have it test to see if it is being run from a floppy and warn the user that performance will be miserable if that happens to be the case (because floppy access mangles sound output horribly). How can I do this? I'm willing to write an XCMD if someone can point me in the right direction. If there's an easier way, though, I'd like to use it. -- Jim Elliott "Like a bridge he'll come between us, not a wall" elliott@veronica.cs.wisc.edu

(using two XFCN's from the SupportTools eXternals stack): CurrAppPath returns the full path name of the currently running HyperCard. (For example, "HD40:HyperStuff:HyperCard".) Strip away the stuff after the first colon and put the rest into volumeName. Put SCSINameToID(volumeName) into "temp": if volumeName isn't a SCSI drive, temp will contain "volumeName is not a SCSI drive" and you'll know that you are working from a floppy. -- Bill (johnston@oscar.ccm.udel.edu)

Of course, there are SCSI floppies and non-SCSI HDs out there... This was a huge discussion on c.s.m.programmer last Fall; conclusion seemed to be that you can't distinguish hard drive vs. floppy: the best you can do is check for functionality. (i.e., if it ejects, it's a floppy, a CD, or a removable hard disk; check for size to be sure). -- /============================================================================\ | Francis Stracke | My opinions are my own.

How can I do this? In the startup script, put on openstack if the diskspace < 1200000 then -- either your hard disk is chock full and you need to -- do something else or warn the user of this possibility answer "This needs to run on a hard disk" with "continue" or "quit" end if end openstack Dan Dlugose UNC Educational Computing Service -- Dan Dlugose Internet: dlugose@uncecs.edu UNC Educational Computing Service Box 12035, Research Triangle Park, NC 27709-2035

Sounds played from the SCSI CD do nicely. Ant Man! Dan LaSota ffdkl@acad3.alaska.edu
