Since the very last time I used Apple][ with Disk ][ floppy drive was something like 20 years ago, so I don't quite remember how it worked. Basically the question is that assume an application program has 2 diskette which are double sided. Do we need to put the first diskette in Drive1 and put the second diskette in Drive2? Or we need to not only flip the diskette when prompted but also we need to remove the first diskette from Drive1 and then put the second diskette into Drive1? So I guess the question is really that is Drive2 not needed for all the application programs or it is application program dependent?AFAIK it is application *and* OS dependent. If it is a DOS3.3 application, unless the program has a setting to look for drive 2, it will probably default to running off a single drive and ask for the appropriate disk to be inserted as necessary. If it is a ProDOS application, I *believe* that ProDOS will search available drives looking for the appropriate disk if it does not find it in the current drive. I could be wrong here, but this seems to be the behaviour for many programs. Can someone please confirm/deny this?That's right--ProDOS scans drives.
However, ProDOS scanning is pathname based. As long as a proper path is supplied to ProDOS it will find the given file. Otherwise, it would only look in the current (or last used) path. BASIC.SYSTEM will also work similar to DOS 3.x using slot,drive combinations.
