In response to some recent questions about Merdian's AdaZ, it's for
real. If any PC Ada compiler deserves to be called ``Turbo'' Ada, its
AdaZ. It's not perfect. There's a few minor things that I think need
fixing, but nothing that would prevent me from strongly recommending
it. And I can say this after having reviewed every PC Ada Compiler on
the market. (If you read the review I wrote for PC Week, AdaZ is what
Merdian was originally calling Reach.)
Consider what you get for $149:
- real mode Ada compiler.
- optimizer.
- mainframe-like debugger.
- the best and most complete DOS interface libraries I've seen.
- a utility library: includes command line args, bit operations,
peek and poke operations, and the Text_Handler package from
section 7.6 of the LRM.
- graphics utilities package (SOURCE INCLUDED): includes support
for windows, graphs, circles, ellipses, lines, and rectangles.
- generic package (SOURCE INCLUDED) of elementary functions: based
SIGAda Numerics Working Group proposal.
- spiral bound copy of the RM.
- pragma INTERFACE: supports Microsoft's C and MASM.
- pragma INLINE implemented.
- machine code inserts.
- good implementation of Chapter 13
- tasking: supports preemption and time-slicing
If that's not enough, you get Meridian's Ada compilation environment
(ACE). This is an editor that provides:
- 10 user windows
- customizable Ada structured editor.
- general purpose editor with
o word processing capabilties
o UNIX like search and replace
o line drawing capabilities
o editor macros
o much more
- hypertext help
- hypertext Ada LRM
- access to the compiler tools
- customization of the environment, key assignments, and default
compiler options
As to the code, it's good enough for anyone that wants to develop
real mode DOS applications.
If you know someone who needs an Ada compiler for training purposes
or who just wants to find out what this A-D-A language is all about,
recommend AdaZ to them. This compiler will make a favorable first
impression on new Ada users, and that's important!
I think Meridian deserves lots of credit for introducing AdaZ at
such a reasonable price. Obviously there's something in it for them.
I'm sure they're trying to build a customer base that will eventually
move up to their 286 version. Just the same, this is something that
should help make Ada much more widely available and understood. Maybe
if Merdian gets a big enough response, the price will stay at $149.bwb@sei.cmu.edu (Bruce Benson) (12/07/90)

The saleswoman actually told me that if I was familiar with Turbo Pascal, then I would be comfortable with AdaZ. She obviously never saw Turbo Pascal. This may be a good Ada compiler, but it sure is several generations behind Borland/Microsoft/JPL/others in support environments. <what you get for $149 details removed> >If that's not enough, you get Meridian's Ada compilation environment >(ACE). This is an editor that provides: <details removed> If any of you have used (as I do) the shareware blackbeard editor, then you'll recognize and be comfortable with ACE. >As to the code, it's good enough for anyone that wants to develop >real mode DOS applications. The "hello world" generates an .exe of about 42K. The manual gives hints at how this can be reduced. The compiler et al takes up about 5Mb of space and needs a few 100K of disk space for swapping. I only gave it about a 100K of disk space, and ACE reported "out of memory" not "out of disk space". The only other glitch I've noticed is the amake program doesn't like the MS-DOS ctrl-z file termination indicator for text files. It calls it an unknown keyword - which is confusing since the ctrl-z is generally nonprintable: Unknown keyword "" (I piped the output to 4dos list and it showed the ctrl-z graphic arrow). I ran the Dinning Philosophers portable example provided here on usenet and it prints the opening positions, then did nothing. I'm not an Ada guru but I suspect the compiler configuration I used was incorrect, vice anything wrong with AdaZ. > If you know someone who needs an Ada compiler for training purposes >or who just wants to find out what this A-D-A language is all about, >recommend AdaZ to them. This compiler will make a favorable first >impression on new Ada users, and that's important! If I were a command-line junkie, I might agree. While Borland and Microsoft environments are not the best editors, the environments can still significantly boost the productivity of the programmer - especially the new programmer (in any language). Meridian's ACE reminds me of the environments I used during the days of micros using CP/M. > I think Meridian deserves lots of credit for introducing AdaZ at >such a reasonable price.

I bought AdaZ because I needed to get to know Ada better than I do now, so to Meridian, thanks for the low price. But if you think I'm going to use this to develop with (my own stuff, or utilities, etc) then I think we've overrated the role of the compiler in the development process. * Bruce Benson + Internet - bwb@sei.cmu.edu + + * Software Engineering Institute + Compuserv - 76226,3407 + >--|> * Carnegie Mellon University + Voice - 412 268 8469 + + * Pittsburgh PA 15213-3890 + + US Air Force

The question is: Will Meridian continue this practice? My mailing indicated that on Dec 25th, the price jumps up to $495 (Merry Christmas :-) ). I know a lot of students in the local area that would jump at the chance for a cheep Ada compiler, but most want to wait until Jan. As for myself, I have used the Meridian Ada compiler for some time, and have found it to be sufficient for light to medium projects. I am sure that, over time, this will become a more polished product. The folks at Meridian deserve a pat on the back (especially you, Pammy!) for listening to the masses of people who wanted Ada, but didn't want to take out a second mortgage. Of course, somehow, I can't imagine Alsys or Telesoft slashing prices (Imagine Apple cutting the cost of a Mac IIfx in half).. > If you know someone who needs an Ada compiler for training purposes >or who just wants to find out what this A-D-A language is all about, ^^^^^^ Sadly, I still get those kind of questions from people (CS types, no less!). Well, to my intended point: I am aware of a company (name escapes me -- they made a big impression) that was marketing a CASE tool called Ada_Z...have they changed their name, gone out of business, or can't afford an ambulance-chaser to sue Meridian? :-) Dave Weller | *This message void where prohibited by law.

It'd be nice if folks called Meridian to ascertain what's going on.
They have told me and anyone who asked that their student price will be $149.
forever, and that after the attention they got at Tri-Ada the "introductory"
price will hold for at least another month. My guess is that it'll hold for
longer than that, maybe forever.

Well, neither Alsys nor TeleSoft will run on an unadorned AT; Meridian
charges a lot for _their_ 386/extended mode system too. Sad but true.
As for Apple: at least they are trying to do _something_ at the low end. Now
if only somebody would bring out a usable Mac Ada (not an MPW tool but a
reall Mac Ada compiler)...By the way: Meridian will sell their Mac Ada to
students for $200.

Me too. Some of 'em are in the government.

Hmmm. The company is TASC, and indeed they sued Meridian. (They had made
such a big splash that Meridian didn't know the name had been taken!)
Meridian is apparently changing the name in some way to satisfy TASC.
Stay tuned for the name change. Meridian has been trying to get people
to say "Open Ada" recently, like at Tri-Ada.

I am unable to compile any ADA source file using Meridian's ACE software that comes with the ADA Z package for the PC. I always receive an invalid function number error message. I can't even compile their test program. The command line version of their compiler seems to work fine. I am also unable to link an executable from inside ACE (using code that has been compiled using the command line compiler). It keeps telling me that I am out of memory. I have 585K RAM free before I run ACE. It's pretty hard to squeeze more memory than that out of a PC. Their "amake" program maintainer also seems to get confused. It sometimes doesn't do everything required, and sometimes does too much. I have sent a message about this to Meridian. I haven't heard anything back so I thought I might see if anybody else is having problems. (In all fairness, my message may not have made it to Meridian). Thanks for any help, Steve

I am using a 4.77 mhz PC-XT with 640K and CGA, and I doubt you can get a system much more "minimum" than that. The compiler and ACE work great in my opinion (I'm just a little spoiled because of the extra template definitions in the VAX Ada LSE template...nice to get header documentation in at the expansion of a token!) The product (in my opinion) is a great deal if what you want is an Ada compiler for your PC at home. The prices are good (even since they dropped off the discount), the product is validated, and most importantly doesn't appear to be too buggy (yes you can have validated compilers that are buggy, especially with related utilities etc.). -- --------------------------------------------------------------------------- Lawrence Fisher Internet: fisher@edwards-vax.af.mil Digital Equipment Corporation ^ Principal Software Specialist Currently working here | (Edwards AFB, CA) Specializing in Realtime Disclaimer: I don't speak for Digital or the U.

I've used the ACE editor on a 1MB 16Mhz 386SX with great success. Another response indicated a fews things to check which seemed reasonable. If you don't get a response from Meridian, call them at 1-800-221-2522.

Two weeks ago I istalled AdaZ on my 20 Mhz 286 AT. It was not untill I removed "ALL" TSRs and a device driver that I was able to compile. The machine has 1 mag of extended RAM but I have not been able to find out how to use it. My home machine is a 10 Mhz 286 with 4 meg of extended mamory. AdaZ installed and ran without unloading anything. If anyone has any suggestion on how to use extended memory, please pas it along. DonB
