* There are a number of disk utilities available that store images of disks that
* utilize file systems that are not ProDOS, at the end of a ProDOS volume.
* There's DOS Master, by Glen Bredon, that stores images of DOS 3.3 disks at the
* end of a ProDOS volume. Similarly, Pro/Part, by Steven Hirsch, stores images
* of CP/M volumes. Also, there's Pascal Partition Manager (PPM) that stores
* images of UCSD Pascal volumes. I've decided to refer to the area used to store
* volume images, by all three of these systems, as a Foreign Volume Area or FVA.
* All three of these systems modify the Block Allocation Map of a ProDOS volume
* to keep ProDOS from assigning blocks used by FVAs for use by files being
* written by ProDOS. Pascal Partition Manager is different from the other two
* in that it has a file type ($EF) and file kind (4) assigned to it by Apple.
* A directory listing of a ProODS volume containing an FVA managed by PPM will
* show a file name of "PASCAL.AREA". A directory listing of a ProDOS volume
* containing an FVA managed by DOS Master or Pro/Part will show absolutely nothing.
* Running a popular utility named "MR.FIXIT", also by Glen Bredon, against a
* ProDOS volume containing an FVA will report an error. Specifically, "MR.FIXIT"
* will complain that all the blocks used by an FVA as allocated but not in use.
* To solve this problem for Pro/Part I wrote a Foreign Volume Area utility
* program that generates a directory entry for the Pro/Part area. That entry has
* file kind 4, file type $EF, file name "PROPART.AREA" and an auxiliary file
* type $4853 (Steven Hirsch's initials). Today I realized that it's likely that
* the same thing could be done for DOS Master. Study of the source code for
* DOS Master will reveal it that's true. If it is, I propose that "DOS33.AREA"
* be used as the file name and $4247 as the auxiliary type (Glen Bredon's initials).
* As I compose the text of this message I realize that another solution is to
* modify "MR.FIXIT" to be aware of FVAs. But doing that would not allow someone
* doing a directory listing of a ProDOS volume containing an FVA to be aware
