Documentaion for YASE (Yet Another Sector Editor)
Format:
yase [d:]
where d: is the drive to be read.
Ok, I know you're wondering, "oh god, not another sector. Why, I
can just use Norton." Well, yes, you could, but Norton Utilities (c)
is not shareware, so you really can't distribute it, at least
not legally. The same can be said for every other sector editor
I've seen around. Thus I felt the need for a simple, shareware
editor. Yes, I admit it, this program is a bit primative, or
rather, very, but that's the exact reason I created it. Recently
I needed to look at some disks that were formatted for UCSD p-system
rather than DOS. First thing I did was to use Norton Utilities (c),
or rather I tried to. Norton refused quite adamantly to read
these disks. So, I created YASE to attempt to read these disks.
Lo and behold it worked. I then spruced it up some to it's
current form. Enjoy!

Comments:
YASE was written for a CGA system. It will only work on
systems where text video memory is located at segment B800H, as it
writes directly to video memory for speed. Also, the program
currently does NOT check for disk length, so it's possible to
attempt to read beyond the end of a disk, which results in an
error. If anyone knows of a way to find out how many sectors are
on a disk (perhaps through a BIOS call?), esp. in Turbo C (c), I
would be very much appreciate the information. Also, the program
is set up so that reads beyond 20 meg (about sector 47,000) are
not allowed for the above reason. Any other bugs or comments,
please mail to me.
