Re: Volume Number support for .dsk images



A '$' is problematic with less than super-proficient users in UNIX/Linux environments. Basically, a '$' denotes substitution from the environment: $SOMEVAR is equivalent to DOS .bat files' %SOMEVAR%.

The '$' can be quoted to get around this, but most beginning to mid-level users won't think of this and get themselves into trouble when copying/renaming/whatever files at the OS prompt.

Like emu writers don't have enough to do, here's another wish list item:

Why not add support for Volume Numbering of .dsk images?


    Sure, we can use .nib images when volume number has to be preserved; but,
.nib images take up a lot more space and are not nearly as easy to use when you
want to transfer between machines and/or go from image to diskette.

    At present, we are dealing with piles of .nib images mostly because it's
the only way to preserve volume number.


    One way to retain VN info without any changes to .dsk format would be to
make it a filename option-- i.e. an extension which tells the emulator the
volume number.

    For instance, suppose you know that the volume number for Robot Muncher's
boot disk needs to be 29. Instead of going through the bother of making a .nib
image, you make a .dsk image and name it "RobotMuncher1_V029.dsk".

    An emu which supports VN recognition sees the "_V029" near the end of the
file name and sets that as the default VN for that drive so long as the image
is there.

What about Dapple, which doesn't support LFNs?  (Dapple ][ will
possibly support LFNs in an LFN-aware environment.  I, however, don't
have one.)

My suggestion is to use the format "rbmunch1.$1C" (volume number in
hex) and have the emulator recognize *.$?? as .dsk files.
