Paul,
You might want to try a program called "Treesurgeon". It reads all
directories and checks all files. It then lists the duplicates and allows
you to compare them before deciding to delete them. I'm afraid it can get
tedious the first time if there are lots of duplicates, but it's worth it.
After that, it's a cinch to check every month or so to eliminate the
inevitable duplicates that always manage to sneak into hidden 'niches'.
Cheers,
Dave Klein

Subject: DOS Environment Variable
Greetings from the frozen north!
I need some way of putting the current directory name into a DOS environment
variable. Something like CDIR=C:WORKACCT
Any ideas?????

Subject: Ega registers
Can anybody tell me where the ega registers are stored in memory. I know video
memory is stored at a000 in 640x350 mode but I heard that this memory can not
be written to directly. What exactly do these registers do? Also does anybody
know using bios interrupt 10 how to access Amstrad PC1512 16-colour 640x200
graphics?

Subject: Formatting PS/2 disk
Microchannel PS/2's come with a reference diskette. Boot up from that
disk, and get to the menu where one of the options is "test the computer."
At this point type CTRL/A and (shazam) it will start up the advanced
utilities which includes the low-level disk formatters. Why IBM put this
important software on the disk but hid it in this silly way I'll never
understand. I suppose I should be grateful that they don't expect me to
pay $100 for diagnostics like they did on the XT and AT.

I think that I understand your problem. I was faced with a similar
situation not long ago. I got by it in a slightly kludgey but nice way.
I wrote my batch file and put a copy of it on both floppies. I then ran
it off the a: drive. When the user switches diskettes, DOS resumes
operation transparently. (The switch takes place during a PAUSE command.)
If you don't trust that method, you can do it another way. Write two
batch files, one for each floppy. At the end of the first one, instead of
using the PAUSE command, tell the user to type CONTINUE to continue, and
have the batch file on the second floppy called CONTINUE.BAT. It's less
elegant, but straight-forward.
Ultimately, the "right" way to do this is to write a program which you can
compile into an executable that will do all the copying with system calls.

Subject: Questions about communications
I Personally like to use Yterm for my connections with our IBM (CMS)
system, and Qmodem for my communications with everywhere else. I have
been recommending Telix to most NEW users of Communications software, as
it supports automatic Zmodem (Zmodem is built in, and will automatically
start when you tell a bbs to send it to you)
Zcomm seemed more complicated to me when I tried it a couple of years ago,
and I have not taken the time to try it recently. I tested a version of
the current version of telix (3.11) a couple of months ago. That is the
basis of my recommendation, but I still prefer Qmodem. Telix uses
compiled scripts, and as a consequence, the scripts run very fast. Qmodem
cannot keep up while scripting at 2400bps on 4.77 mhz PC, so that may
influence you.
I tend to do a lot of file transfers, and so am constantly trying to get
the best transfer speed and reliability. Zmodem is at the current leading
edge, and Kermit is still based on a 7 bit system. Kermit does what is
needed, but when you have the ability to connect at 8 bits, Zmodem is as
fast as you can go, while kermit generally for me achieves only a 50%
effeciencey (speedwise)

Subject: Low level format on PS/2
To do a basic low level format on a PS/2, boot the reference disk and
type control-a at the first menu. (Or was it alt-a?) This should take
you to a menu with low-level format on it. Be advised, though, that this
will only format IBM drives. It seems that IBM preps the drives they sell
with some info on their size, # of heads, etc. before you get them. I
tried to put a ST-251 in my model 80, but I couldn't get IBM's software to
format it.
Although I haven't tried it, Ontrack Computer Systems (Eden Prairie, MN)
has a program that will format any hard drive in a PS/2 micro-channel
based computer. The price was something like $150.

Subject: Packed .EXE
I am looking for information about Packed EXE files and ideally a program
to UNPACK exe's which have been packed using ExePack.
I have a couple of programs which I would like to patch and have no way of
finding the information that needs to be changed because they are packed
EXEs.
The MicroSoft C manual describles ExePack as a utility which compresses
sequences of identical characters from a specified executable file. It
also optimizes the relocation table. Using EXEPack, you can reduce the
size of some files and decrease the time required to load them. Is it
possible to un-do the packing?

Hello there,
Does anyone know terminal emulator for vt200 (or 220) for Hercules ? I
got one (qvt26) but it worked only with nonenchanced keyboard.
And an other question. Is there anywhere a pd 386 assembler ?
