Re: GS/OS: looking for info on VCB and FCB

David,

I have a copy of an shk file called MSDOS Tools for the Apple IIGS.
Here's the first line of the Read Me file that is part of the shk file
and can be read after you've expanded it.

Introduction
============
The MSDOS Utilities V2.00 are a set of command shell utilities that
allow files on MSDOS disks to be read, *WRITTEN*, listed, deleted,
renamed, etc. Other utilities allow disks to be copied, formatted and
(re)labeled. Any size disk should be supported, including partitioned
hard disks.

I don't remember exactly where I got this shk from but if you'd like a
copy I can e-mail it to you as a zip file, which will open up to the
SHK file.
