[net.micro.cpm] ZCPR3

David,

I am writing a book on ZCPR3, and this will address your questions
in much greater detail.  In a nutshell, ZCPR1/ZCPR2/ZCPR3 do not address
programs which use overlays.  Such would require a BDOS modification.
There is a way around this problem, however, with ZCPR3.  As I mentioned,
one feature of ZCPR3 is the alias.

The alias allows the user to define a sophisticated command line which
is executed in place of a simple command issued by the user.  I am running
WS and dBASE II, as well as BDS C, C/80, and PASCAL/MT+ under ZCPR3,
and, by using a combination of aliases and ZEX command files, all are
fitting into the ZCPR3 environment.

Each commercial program must be addressed independently,
since they all handle things differently.  WS, for instance, will, when
not finding its overlays in the current directory, drop down to disk A,
current user and look there.  Hence, I use WS only from a directory called
TEXT, where TEXT is B7: and WS.COM and its overlays, including a spelling
checker, are in A7:.  The search path is A$ A15 (including current dir
by default), so issuing WS from B7 will find WS.COM in A7 (the A$
part of the path expands into A7 when the command is issued from d7).

When it comes to program editing, I use WM, which requires not overlays
and optionally can use a HLP file (which will be found in A$ if not found
in the current dir).  WM is in the root (A15), so it is found from anywhere on
the system.

dBASE II was quite different in that it had to have its overlays in
the current directory.  To get around this problem, I created an alias
which, in response to the command DB2, will issue the following
command sequence:

		A9:;dbase setup;$d$u:

where:

		A9: -- logs me into the directory containing DBASE.COM
			and its overlays
		dbase setup -- runs DBASE.COM, and SETUP.CMD contains
			the command "set default to B:", which places
			me into B9: to do the work; when I issue the
			"quit" command, the last command is executed:
		$d$u: -- returns me to the directory I was in originally

Finally, with the three languages I mentioned above, all support the ability
to indicate where the required overlays are located.  ZEX command files are
used to do the compilation, linking, and cleanup.  Also, for each language,
the files supporting the compilers and linkers are in An: while the work areas
are in Bn:, such as A2: containing BDS C compiler and linker while B2:
contains the files I am working on.

You will see more on this when the book comes out.

re: all the discussion of how to get ZCPR3, how about someone giving a
general description of ZCPR3 itself - its capablities, requirements, and
installation. Does it run under standard CP/M 3.0 ? Does it need
banked memory or can it run in non-banked environments? Does the BIOS
have to modified or have extensions added? 

For the sake of us without FTP access, please post on info-cpm rather
than referring us to DOC file somewhere that we cannot get to.

Thanks

Hi, Charlie,

	Thanks for the comments.  Re CMDSET, I'll look at it and
modify the book to include something about it if it was omitted ... if
not, I'll be sure the index references it.  Re the path, I haven't
encountered any problem with it.  Usually the BDOS error comes if the
path is not properly terminated (by a binary 0).  You might want to
check that.

	I have been receiving several good comments on ZCPR3
personally ... perhaps they are not going out publically.  Also, the
magazines are picking up on it ... User's Guide has already commented
on it in their review of the Ampro, and I know that others
are planning feature articles.  I
guess you will see more in the months to come .. by then the book will
be out, and people can really attack it.

	The phase 2 stuff is coming along very nicely.  I think you
will be very pleased with it.  Most of it consists of screen-oriented
utilities like VFILER, VMENU, DU3, MU3, and I am working on an
RCP-resident version of MU3 so that an RCP-resident shell which can be
used to debug programs as they reside in the TPA will be available.

		Enjoy!

   Has anyone succesfully installed ZCPR3 on a DEC VT180 (i.e. Robin)?

 I have been tied in knots with school work and don't have the time to
download,install etc.. But I would love to use it.

 Please reply to the undersigned..


	 Mucho gracios!

Has anyone gotten zcpr3 running on the Kaypro yet?

RCONN@Simtel20.ARPA (08/05/84)

From:  Richard Conn <RCONN@Simtel20.ARPA>

	Echelon has it running on the Kaypro-10.  I'm not aware of any
other Kaypro-specific installation, but the auto-install should
eliminate that problem readily.  The auto-install is still in beta
test and I'll be able to report more when I see it.

     -->  1. Is ZCPR3 hard to bring up on my computer?  What
             are my options?

                             ANSWER

If you try to bring up ZCPR3 manually (following the installation 
instructions   in  ZCPR3:  The  Manual),  the  answer   is   yes.  
Experience in assembly-language programming is necessary.  Source 
code to your BIOS is necessary.  An understanding of CP/M and  Z-
System concepts is necessary.
     However,  you may not have to bring ZCPR3  manually.   There 
are options...

.foQuestion 2: How Much Memory is Used?                       Page #
     QUESTION 2: How Much Memory is Taken Up by a Z-System?

     -->  2. How much memory does a Z-System take?

                             ANSWER

A  Z-System can take up a lot of memory, but it can also take  as 
little as 1K, depending on how it's installed.
     I  have  run the following programs in  a  full-up  Z-System 
(which  takes 5K more than a similar CP/M system), and they  have 
worked well for my applications:
                 dBase II              BDS C
                 WordStar              C/80
                   SpellStar           Pascal/MT+
                   MailMerge           MultiPlan
                   StarIndex           ASM, MAC, M80, ZAS
                 MBASIC                Z-MSG
                 CBASIC2
     There  are  some programs which hog so much  TPA  that  they 
can't run under my full-up Z-System, but I don't use them or need 
them for my applications.
     The  impact on memory is really not that significant if  you 
look at a true picture...

  2.5K           8K = 12.5%          9K = 14.1%    13K = 20.3%
  3.5K           9K = 14.1%         10K = 15.6%    14K = 21.9%
  4.5K          10K = 15.6%         11K = 17.2%    15K = 23.4%
  5.5K          11K = 17.2%         12K = 18.8%    16K = 25.0%

     Note:  nK = p% indicates the size of the system in K (BIOS + 
BDOS  +  CPR) and the percentage of the total memory taken up  by 
the operating system.   In my case,  I am running a Maximum ZCPR3 
with  a 5.5K BIOS overhead,  so this leaves a 48K TPA (64K  - 16K 
System) which expands to 50K if the program overlays ZCPR3.   All 
my programs, including WordStar and dBASE II continue to run, and 
I have full ZCPR3 features.
     Even  with this argument,  people will still ignore the vast 
gains  in  functionality and capability offered by ZCPR3  and  Z-
System  and concentrate on their single-minded fixation with  TPA 
(for  reasons no one has adequately explained to me).   A  future 
ZCPR3 release,  ZCPRB3, will offer a banked memory system with at 
least a 60K TPA (now,  that should make them happy).  Note that I 
am not moving to a banked system on their account,  but as a step 
toward multitasking--something I really want.
.foQuestion 3: How Much Disk Space is Used?                   Page #


    QUESTION 3: Must I have a hard disk to run the Z-System?

     -->  3. Do I have to have a hard disk to run the Z-System?
             How much disk space is needed?

                             ANSWER

No.
     The Z-System runs better on a hard disk...because everything 
runs  better on a hard disk.  Also, a hard disk runs better on  a 
Z-System  because of all the programs and features which  support 
the hard disk:

          Named directories with passwords
          Public directories under ZRDOS+
          Paths
          Shells
          Special commands, like CD (Change Directory)

     Most Z-System features are practical regardless of the  disk 
used.
     The following shows some disk configurations, from a full-up 
hard disk (over 1 megabyte of support files) to a minimum  system 
(less than 40K-bytes of support files)...

.foQuesiton 4: How Can I Find Out More?                       Page #

     QUESTION 4: How can I find out more about the Z-System?

     -->  4. How can I find out more about the Z-System?

                             ANSWER

There are lots of ways:

          o talking to Z-System users
          o magazines
          o books
          o user's groups
          o Echelon Newsletters (Z-NEWS)
          o Echelon, Inc.

     While  the  first  documentation on the  Z-System  was  very 
technical,  Echelon  and its friends are producing more and  more 
user-oriented  documentation which is aimed at the  non-technical 
user.   Many,  many magazine articles have also come out with the 
intention  of aiding the non-technical user in understanding what 
the Z-System does for him.
     The documentation is abundant...

Sorry about the mass distribution ... his return address was to INFO-CPM.

RCONN@SIMTEL20.ARPA (Rick Conn) (05/01/86)

The BIOS mod for Z3 is required to set aside AND initialize the buffers used b
by Z3.  When the command processor first begins execution, it assumes the
command line buffer to contain a valid command line, and the address
of the first char (also in a buffer) must be set correctly.  There are also
other buffers whose content must be valid before the command processor is
executed the first time.
