- All ZCPR3 and CP/M users: I have taken the notice of ZSDOS'
- release that Carson Wilson wrote up and added to it information
- about datestamping, which I feel Carson doesn't enough emphasize,
- including an alphabetized list of supported available programs.

-
- ANNOUNCING: ZSDOS, NEW CP/M-COMPATIBLE OPERATING
- SYSTEM WITH OPTIONAL BUILT-IN DATESTAMPING
-
- The following notice of the release of ZSDOS was posted on
- Lillipute Z-Node in Chicago, headquarters BBS of both The
- Computer Journal and the Z-System Special Interest Group, by
- Carson Wilson, author of Z80DOS and now one of several joint
- authors of ZSDOS. For users with a real-time clock ZSDOS will be
- a godsend. For those without it will be an absolute joy as full
- datestamping without timestamping will finally be theirs. One
- thing that I feel Carson's advertisement does not emphasize is
- what I consider to be the most important thing that a user would
- gain from switching from ZRDOS to ZSDOS: the built-in
- datestamping, and with almost no loss of TPA. With my clock
- driver in my BIOS I have added complete time- and date-stamping
- on my system at a cost of 256 bytes (.25k)
-
- Whether the commercial ZSDOS/DateStamper (the two use the same
- protocol) is superior to the public domain Z80DOS datestamping is
- a question over which wiser men than I continue to spill gallons
- of ink debating. For myself and many others, however, the issue
- is easily resolved by one factor alone: the number of programs
- that support ZSDOS/DateStamper protocol is far greater than those
- with Z80DOS support. I have compiled a list of these programs.
- With ZSDOS users of ZCPR3 will have datestamping support for the
- following programs, most of which except MexPlus are non-
- commercial and available through the BBS circuit or on the
- ZSDOS distriution disk:
-
-
- APPEND Concatenate files like PIP can, but inserts the date
- of concatenation as a line of text between each
- file.
-
- ARUNZ Allows for display, manipulation and other use of
- several date-related parameters in macro command
- scripts; $dd is the current date, $dm the month, $dy
- the year $dh the hour, $dn the minute, etc.
- Extremely useful and powerful.
-
- CRUNCH23D With the datestamping version of CRUNCH, we can
- embed the date stamps in the compressed file itself
- (it's not dependent on the directory entry) and we
- can thus transfer datestamp information via modem.
-
- DATE Displays current date on screen.
-
- DATSWEEP More like NSWEEP with datestamping features added.
- Displays create, access and modify date of all
- files. Can copy or archive files by date using '=',
- '<' or '>' operators ("copy all files modified in
- the last two weeks of January"). Can manually
- change a file's datestamp.
-
- DBASE Yep, we have a patch for this venerable program. No
- longer will you have to enter the date when the
- program loads as you've been doing for years.
- ZSDOS/DateStamper will do it for you.
-
- DIFF Compares files by date or otherwise
-
- FD "FILEDATE." Perhaps the most exciting of them all.
- A directory utility that not only displays the
- creation, access and modification dates of files in
- a directory, but is sensitive to and can sort by
- date. Options to sort from most recent files to
- oldest, oldest to newest, list only files modified
- or created today, only modified/created since a
- given date, etc. It truly opens up a whole new
- world of computing.
-
- LBREXT Preserves a file's datestamp (create, access and
- modify) upon extraction from a LBR).
-
- LOG Perfect way to keep track of how long you spend on
- each "type" of task on your computer. Will "log"
- time spent on each of several self-chosen or given
- categories into a file for later viewing and
- displaying. Excellent for record-keeping for IRS.
-
- LPUT Preserves a file's datestamp upon insertion into a
- LBR.
-
- MCAT, XCAT Complete floppy or hard disk cataloging system;
- ZSDOS version of Irv Hoff's classics. Allows user
- to display to the screen, for example, all files in
- one's collection of floppy disks created before July
- 1988, or during the month December, 1987, etc. When
- used normally, will display files' datestamps along
- with their names.
-
- MCOPY Copy program allowing simultaneous copy of multiple
- unrelated files using filelist feature of ZCPR3.
-
- MEXPLUS Scripts can display, wait for and measure time.
- Perhaps my greatest programming feat was a MEXPLUS
- script to log on to PCP Pursuit. The script can
- tell you how long you have been on a BBS, how long
- you were on the last logged BBS, the current time,
- how long you have been attempting to connect to PCP,
- how long was the last attempt, etc.
-
- NT Loads and saves virtually instantly, NT is a quick
- "note"-maker and mini-editor. It begins all files
- with the current date and time at the top.
-
- PPIP Copy program, sensitive to archive bit if desired;
- always preserves date of source to destination.
-
- PRINT Prints date and time at top of each printed page.
-
- SAVESTMP For editors other than ZDE that do not preserve
- creation date. Stores this stamp information
- temporarily in a buffer, then re-imprints it onto
- file upon exit.
-
- SDD Similar to FILEDATE, but more limited. Only
- displays filedates, cannot sort by date.
-
- TIME Displays current time on screen.
-
- UNCRUNCH Uncompresses the file and restores its datestamp.
-
- WAIT Will "wait" until a specific time before performing
- a given operation. Useful for SUBMIT scripts and
- other multiple-command line operations.
-
- ZCAL With no parameters, displays a calendar of the
- current month with the current day highlighted.
- With parameters it will display a calendar of any
- month in the 20th century.
-
- ZDE Coming shortly. ZCPR3/ZSDOS version of VDE.
- Automatically preserve a file's creation date after
- editing.
-
- ZFILER Extraordinary file management utility shell. Like
- NSWEEP taken to the 100th power. Displays current
- time on the screen, preserves datestamp of copied or
- "moved" files.
-
- ZMANAGER Another file utility menu/shell, displays current
- time on screen, etc.

- Z-System Disk Operating System
-
- AFTER a year of intense work and nearly three years of background
- research, ZSDOS is ready! The package includes over 300k of
- files and nearly 150 pages of documentation, and is available for
- $75.00 plus $3 shipping from Plu*Perfect Systems (owners of ZRDOS
- may upgrade for $60.00 plus $3 shipping).
-
- ZSDOS replaces the BDOS segment of CP/M 2.2, and offers
- programmers and users of all types of Z80 computers a host of
- enhancements not yet found in any CP/M compatible operating
- system, including:
-
- o Built-in DateStamper-type file datestamping. If desired, full
- datestamping can be implemented at the cost of under 512 bytes of
- TPA, or if your system already has a real-time clock and driver, no
- TPA at all is required.
-
- o Public and Path Access to files. Now programs can access any file
- from anywhere on your system. Public and path may be combined for
- even greater efficiency, and either form of access may be set to
- read-write or read-only for greater security.
-
- o ZSDOS is dynamically configurable by the user or by programs. File
- access modes, the path, fast fixed disk relog, Wheel protection,
- disk read only sustain, the clock address, file datestamping, and
- other capabilities of ZSDOS may be reconfigured even while programs
- are operating.
-
- o Menu-Driven Installation. Even clock driver installation takes
- place automatically, and no assembly language skill whatsoever are
- required to get a full ZSDOS system up and running.
-
- o Eleven fully tested utility programs are included to help you use
- the full power of ZSDOS to automate file and system maintenance and
- daily planning.
-
- o The ZSDOS User's Manual explains in plain terms how and why ZSDOS
- works, how to install ZSDOS, and how to use the utilities, and
- consists of 147 full-size looseleaf pages of laser printed text
- including a table of contents, a glossary, an annotated
- bibliography, an index, and many useful appendices.
-
- In addition, ZSDOS includes all of the capabilities of CP/M 2.2,
- ZRDOS, P2DOS, and Z80DOS, and removes all of the defects of those
- systems:
-
- o Floppy disks are automatically reset when changed.
-
- o Error messages are in plain English and give a full report of the
- function, drive, and file involved, and read or write errors are
- retryable. Error handling may be taken over by the application
- program as with CP/M Plus. ZSDOS error return codes provide more
- information than those of other BDOS replacements.
-
- o ZSDOS supports file sizes of up to 32 megabytes and disk sizes of up
- to 1 gigabyte.
-
- o Fast fixed disk relog allows users of hard disks to skip the time-
- consuming relogs required by CP/M.
-
- o All ZRDOS 1.7 functions are supported by ZSDOS, so all programs
- which work under ZRDOS versions 1.7 and before are also usable under
- ZSDOS. Popular ZRDOS features such as re-entrancy, file archiving,
- and wheel protection are fully supported by ZSDOS.
-
- o ZSDOS is compatible with Plu*Perfect's BackGrounder II, the
- windowing and task-switching system for Z80 computers.
-
- o ZSDOS adds ten new function calls to CP/M 2.2, and enhances and
- corrects CP/M functions 6, 10, and 37.
-
- IN SUMMARY, ZSDOS offers significant improvements over ZRDOS,
- P2DOS, and Z80DOS, and offers _amazing_ improvements over CP/M
- 2.2! ZSDOS is available now from
-
- Plu*Perfect Systems
- 410 23rd St.
- Santa Monica, CA 90402
-
- and should soon be available from
-
- Sage Microsystems East,
- 1435 Centre St.
- Newton, MA 02159
- voice phone 617-965-3552 (9 AM-11:30 PM Eastern time)
- modem phone 617-965-7259 (24 hours, password DDT)
