Hello!

First of all, let me thank you for your patience and understanding. It has
been a LONG time in coming - but here it is. The first release of the DOS
version of the long-used CPM utility NSWEEP!

To those that have helped make this version possible (Dave McCrady, Chris
Gregors, Jim Lopushinsky, and many others), Thank You for your time. I hope
everyone that will use NSWP in the coming months appreciates the effort these
people have put in.

The release in this archive is a preliminary release, and one feature does
not work - the SQUEEZE function. This should be corrected by 02/10/87, so
those that are waiting for this feature, please hold tight.

Should you discover any bugs (horror!) in this version of NSWP, or any other,
please do not hesitate to leave a message on any of the Edmonton RCPM's, or
drop me a line directly.

More documentation will follow, but for those who know the 8 bit version of
nswp (that documentation is enclosed as NSWP.WS, a WORDSTAR file), here are
the major features:

oThe 'I' command activates timestamp display
oThe 'W'ildcard function will accept a '!' as a 'not' indicator,
so you can w *.*, then remove *.exe from the tagged files with
w !*.exe
oThe move, copy, and log commands accept paths, but the directories
must exist.
oThe 'F'ind command remembers the last specification, and you may
search for the next occurance with just a carriage return at the
find prompt.
oCopy and move check free space on the destination before starting
the copy operation.
oThe new command '!' exits to DOS, so you can invoke another
program (even another copy of NSWP!).
oNSWP uses a dynamically allocated 64K buffer for the copy I/O.
oNSWP automatically senses Concurrent DOS, and uses the correct
escape sequences for highlighting.
oYou should have ANSI.SYS installed (This will be optional in a
future version of NSWP).

There are a few more things, but this should hold you until the new
documentation is complete.

I hope you enjoy this program. If you do, please write me and let me know.
If you don't, let me know that too!

This is NOT shareware, it is good old fashioned Public Domain Software.
Source code, written in C (with bits in assembler), will be made available

source code be sent back to me (I like to know when you find bugs,
or add features).

Well, I didn't expect it so soon, but here is the previously unimplemented
SQUEEZE function.



02/08/87

Ok, here are some new features!

oSqueeze is 5-8% MORE efficient than the older 8 bit NSWP!
Faster, too!

oIf you Zoom on a directory, that directory will be logged.
If you Zoom on '..', you will go to the previous directory.
Zooming on '.' will re-log the current directory.

oA new command (".") has been implemented - This command allows
you to create a new directory. It need not be relative to the
current directory, nor the current drive. You may, for example,
create "E:\new\old\older\oldest". As with the standard DOS mkdir
function, all directories but the last one must exist.

oThe delete function now will delete a directory. NSWP will
prompt you if there are files in the directory. Directories
in the directory you wish to delete will not be deleted.

oNSWP releases an extra 64K during the "!" command, to allow extra
memory for DOS commands.

oNSWP now puts files from a Squeeze, Unsqueeze, or copy that
affect the currently logged directory back into the directory
list of NSWP. As a side effect of this, TAGGED files during
a squeeze or unsqueeze that are not processed (no compression
factor for SQ, not a squeezed file for USQ) are UNTAGGED, rather
than marked as processed ("#"). This means you can do an Again,
then an Erase Tagged to delete all files that were 'dealt with'.
This make NSWP much more intuitive to use.



02/09/87
oNSWP now supports the timestamping version of SQ/USQ. If your
squeezed files are timestamped, the unsqueezer will set the
time and date on the output file. Squeezed files have the
timestamping information appended to them automatically.
If no timestamps are present, USQ will leave the file creation
date set to the current date/time.
NOTE: This is the Homchick/Sharp SQ/USQ timestamp method.
Thanks to their planning, files squeezed with this system
are TOTALLY compatible with earlier versions of NSWP, USQ and
unsqueezers in general.

oA JUMP command has been implemented. This allows you to move
to a specific file, just by knowing the file number. This is
handy to get back to '..' (always file # 2), to do a zoom
to previous directory. Jump also allows you to move relative
to the current file by placing a '+' or '-' sign in front of
the number of files you wish to move. +22 would move 22 files
down the list, and -46 would move 46 files up the list. Wrap
is supported, so -2 from file 1 will move to the second last
file.

02/11/87
oThe FIND command has been extended. If you enter a path-type
filespec, NSWP will search the directory specified and all of
its 'children' for the ambiguous filename supplied. For example,
Find .\*.c will look at the current directory, then all subdirectories
for any file with the extension ".C". You can also express this
as c:*.c, or [current path]\*.c where [current path] is the full
path from the root of the current directory. You can also specify
\*.C, which will return all files in all directories that have
the extension ".C". A report on the number of directories searched,
and the number of files matched will be made at the completion of
the search. The search may be aborted at any time with a ^X or ^C.

02/15/87
oOnce again, then find command has been extended. Now, when you
log (or zoom) to ".." (the previous directory), you can move the
current file position (normally starts at one) to the position
of the directory you just came from, just doing a Find .
For example, if you were in \pd\asm, and did a zoom to "..",
a Find would place you at the entry.

oNswp is now MUCH smarter in dealing with the buffer, and with
squeezing and unsqueezing files. It uses the whole 64K buffer
for the SQ pre-read buffer, then dynamically splits it up for
the I/O buffer on USQ and SQ compression phase. As well, NSWP
forgoes the read if the whole file is already in the buffer
on a SQ operation. This speeds up squeezing files on floppy.

oSource code will be made available to those who need it, at
this point in time. Since heavy work is going on, I would
encourage those who wish to work on nswp with me contact me
at the above address, or at (403) 489-2148.

02/21/87
oWell, the long awaited ARC feature is in! To use, just Zoom
in on an ARC file... NSWP will do the rest. From inside an
ARC, you can use the View, Copy and Move functions, to look at
and move files out of the arcfile. Currently you can't delete
files, or move files INTO an archive. That will be in the next
release. NSWP now uses about 30K more memory. The extract feature
is almost twice as fast as the ARC program, but about half the
speed of PKXARC. As I get time to bit twiddle, I hope to close
that gap.

02/22/87
oA few bugs in the ARC decompression were fixed, including
one that prevented you from extracting any old-style crunched
files. CRCs are now checked. A CRC failure does not stop the
decompression.

oYou can now Print files from within an archive.

02/23/87
oSquashed file decompression sped up. Getting closer to PKXARC...

oBug in delete fixed. Not all files were being erased within
a directory if you choose to delete a directory.


04/21/87
oMinor bug fix in decompression routine.

oY command fixed. Now correctly sets file attributes.
