- Zoo Revision History
-
-
- Current versions as of 1986/09/21: Zoo 1.21, Ooz 1.03, and Atoz 1.00.
-
-
- 1986/09/21 Zoo was revised to eliminate the "Disk full" error message
- Zoo 1.21 that version 1.20 was giving when the output was piped with
- the "-print" and "xp" commands. Except for this fix, Zoo
- 1.21 is identical to Zoo 1.20.
-
-
- 1986/09/06 Substantial performance improvements were made. Compression
- Zoo 1.20 ratios are now much better. Files are now archived about 15%
- Ooz 1.03 faster and extracted about 5% faster. Some minor bugs were
- fixed. Using the "1" (one) modifier with the "D" (delete)
- command now properly updates the archive's timestamp. Adding comments to an
- archive now preserves the archive's timestamp. The character that marks a
- comment in a verbose listing is now "|" instead of ">", because it looks
- better. This is Zoo version 1.20. Archives created by Zoo 1.20 are smaller
- than those created by previous versions, especially for binary files. Zoo
- 1.20 retains full compatibility with Zoo 1.10 and its archives may be ex-
- tracted by all prior versions of Zoo. All documentation for Zoo 1.20
- remains unchanged.
-
- Ooz was also revised to share Zoo's faster extraction speed and is now
- version 1.03.
-
-
- 1986/08/24 Comments were implemented. The user may optionally attach a
- Zoo 1.10 comment of up to 65,535 characters long to any archived file.
- This is now Zoo version 1.10. The following commands are
- available to manipulate attached comments.
-
- Novice mode: the -list command always lists any attached comments. The new
- command -comment sweeps through the archive, displays any previous comment
- for each matching file, and allows the user to: hit return to leave the
- previous comment unchanged; or type "/END" to remove the previous comment;
- or type a new comment terminated by "/END". Expert mode: v is like Novice
- -list, c is like Novice -comment, and ac is like Expert a and Novice -add
- except that it prompts for an optional comment for each file as it is
- added.
-
- If a file added to an archive replaces another of the same name, any
- original comment is preserved and becomes attached to the newly-added file.
-
- Earlier versions of Zoo will list and extract version 1.10 archives and
- delete and undelete files in them but will refuse to modify them in any
- other way thus ensuring archive integrity.
-
-
- 1986/08/20 The update (u) option will now add a file to an archive only
- Zoo 1.03N if the copy being added is newer than the copy already in the
- archive. If update (u) and new (n) are used together, a file
- is added to the archive if it isn't already in the archive OR if it is and
- the copy being added is newer.
-
- A problem with setting of the datestamp of archives was fixed.
-
- Some commonly-used Novice commands were added. These are complete words
- rather than single characters: add, extract, test, print, freshen, update,
- list, and delete. Each word may be abbreviated by any amount. The original
- one-character commands are now known as Expert commands and they remain
- unchanged except for the different functioning of u and n (above).
-
- When an archive is packed, the original is now always renamed to a ".bak"
- extension even if it is on a different disk. This will avoid confusing the
- user.
-
- Some of the messages were made slightly more friendly. This is now version
- 1.03N (N stands for Novice).
-
-
- 1986/08/17 Zoo was allocating and deallocating memory as needed for each
- Zoo 1.02 file added or extracted. This apparently led to fragmenta-
- Ooz 1.02 tion of memory and conflicts with memory-resident software in
- some peculiar situations. Changed the memory allocation
- strategy to allocate all needed memory just once. This is now Zoo version
- 1.02. Zoo's sign-on message now correctly identifies its version number.
- Ooz was similarly fixed and is now Ooz version 1.02. Most people will not
- see a difference in functioning between versions 1.01 and 1.02.
-
-
- 1986/08/16 Zoo 1.00 failed to work with DOS 3.x because DOS 3.x returns
- Zoo 1.01 some new error codes; fixed. Made minor revisions in
- ZOO.DOC. It was also found that ATOZ.BAT would not work with
- the DOS 3.x batch language. Revised ATOZ.DOC to document this
- incompatibility. Released Zoo 1.01 which works with DOS 3.1 (but Atoz still
- doesn't). Warning: ZOO.EXE version 1.01 still says "version 1.00" in the
- sign-on message.
-
-
- 1986/08/15 Initial release of Zoo 1.00, Ooz 1.00, and Atoz 1.00. These
- were developed and tested only on DOS 2.x.
