[Rowan D. Stevens]

 ----  HELP!  ----

I am looking for information about either a user interface methodology, a
name of a research paper, an actual CASE tool or development environment, or
anything which might help me to locate the following:-

A tool or method which will allow a user interface to be developed visually
(similiar to Microsoft's Dialog Box Editor) but will output the operational
interface shell in some object-oriented programming type language (ie. c++)
The method should allow modelling of window-oriented and text user interfaces.
Anything close to this, I would still like to hear about.

If someone out there is carrying out research in this or a similar area, then I
would be very interested in talking further about this.

I can be contacted at:

Hi all, I need some ADA help.
 ( I hope there are some ADA-freaks here ! )

Question 1:
        I have to read a Text-file. All works well with GET_LINE. BUT :
        The file is from an IBM-PC, and it is in German that means there
        are the special German characters ( Umlaute, scharfes S ) in it.
        These characters are encoded as 132, 142, ... all above 127 !
        As far as I know, the type character is defined as an enumeration,
        from 0 to 127, so the special characters are not defined in it.
        Funny enough, when I try to read such characters I do not get
        any error, exception or other faults. When I "put" it afterwards,
        the original special character is written.
        Anyway, I want to make a CASE statement over all characters read:

        case char is
            when 'a' .. 'z' =>     -- This works fine
            when character'pos(132) =>  -- This gives a compiler-error:
                                        -- "Choices have to be static"

        What shall I do ? Making an IF-clause out of it ?
                ( is character'pos(132) legal ? )

Question 2:
        I want to read/write a simple file with no structure, a simple
        stream of bytes. I tried it with :

        type BYTE is range 0 .. 255;
        for BYTE'SIZE use 8;
        package byte_io is new DIRECT_IO ( Element_type => BYTE );
        ...
        byte_io.write ( fh, byte(34) );
        ...

        In the file there is the Value I wanted to write, then a 0, a value,
        a 0, ....     Why THAT ????
        ( Thinks were easy in C .... )

        What have I done wrong ?

I use the SYSTEAM Ada compiler on a VAX running VMS.

Please send all help for DIRECT to me, for I'm not on this List.

HELP!

["Thomas H. Stripe 255-4472", 513]

I am trying to reconstruct my Ada library into the installation family
(Note: I am using ALSYS Ada compiler version 4.3) by the following:

Ada.MEND (LIBRARY => RESTORE.LST, FAMILY => INSTALLATION)

RESTORE.LST contains three file names: D:\ALSYS\PREDEF, D:\ALSYS\ALTERNAT, and
D:\SOME_LIB. D:\SOME_LIB is the library I am trying to mend. The problem is
that I get the following error:

FAMILY_MANAGER: ERROR: The library D:\SOME_LIB does not belong to the
same family (D:\ALSYS\INST_FAM) as D:\ALSYS\ALTERNAT (D:\ALSYS\INST_FAM)

My question is this, Has anybody encountered this, and if so, do you know
of a work-around?

Thanks
Tom

Re: HELP!

[Edward Falis]

My guess is that the user library you wanted to restore with the MEND
command was actually in the PUBLIC family, rather than INSTALLATION.

So...

I assume that the medn on the installation family is already done.  If
not , edit the file listing the libraries so it does not include the
name of the user library.

Reissue the mend command on the installation family.

Now, to mend the public family, create a file foo, place the path
of the user library in the file, enter the family manager, and
type:

mend foo, public

Also note that the mend command applies to families, not libraries.

[Ken McCook;SCDQ;]

I'm working on a MIS project to be hosted on PC using MS-DOS
and Ada. Have Alsys PC286 Ada Compiler.

Does anyone have experience on printed output to standard 
government forms.

I'd prefer to write directly to the printer, but I could live
with having to write to a file and then printing the file.

I had hoped that Ada's Text_IO would have the capabilities 
Turbo Pascal has for directing output directly to the printer 
using Write and WriteLn? (And I'd hoped for direct keyboard
reading as well like someone else on the net in recent days.
Something like Turbo's "Read (kbd, X);".)

I am desperate for examples of source code and some expert
advice on this oneand would greatly appreciate any help.

You probably can write to the printer. See below.

Text_IO does have "hooks" for doing this. Every CREATE or OPEN call
associates a file variable in your program with a string representing
the file's name as known to the operating system. I'm not all that
familiar with the Alsys system, but conjecture based on experience that
they provide a standard file name something like PRN or LPT1. Using
Meridian Ada, you'd write

    My_File_Name: Text_IO.File_Type;

    ......

    Text_IO.Create(File => My_File_Name, 
                   Mode => Text_IO.Out_File,
                   Name => "PRN");

and then all PUTs to My_File_Name would go to the printer. No, Ada does not
predefine the standard names, but probably it could not easily do so
because file naming conventions differ greatly from OS to OS (consider
DOS names with their 8-character limit vs. Unix names, etc. etc.).

So Ada does it JUST LIKE THE OTHER LANGUAGES, leaving it to the programmer
to do the mapping with a Create or Open call. Turbo Pascal is an exception,
not the rule, and can get away with it because Turbo Pascal exists (currently)
only for the DOS world. What is called Turbo Pascal for the Macintosh, for
example, is an entirely different Pascal-like language. And surely the
file names are different between DOS and MacOS.

The bottom line: most likely Alsys provides the standard DOS file names
for you to use. Try it.

The  simple, quick  and  dirty answer is to  write  your  routines in Turbo
Pascal and pragma INTERFACE to them.  Write a general purpose TP routine to
Write_to_Printer and a  Read_From_Keyboard  then encapsulate  the interface
into an Ada package pragma INTERFACEing to your TP routines.

But you may  want to check  out the Ada way of  writing to a  file and have
that file point   to a printer.  I haven't   done this but  I'm sure   it's
possible. 

WRT  reading from the  keyboard, if you want anykind  of real control  over
what is read then you might want to interface to TP or TC or whatever.   If
you  are  simply   reading  in stuff   then  you could use  TEXT_IO.GET  or
TEXT_IO.GET_LINE.

Oops!  Open my  mouth and  insert foot.   I shouldn't have  even  suggested
this.  The Alsys compiler doesn't do pragma INTERFACE  to TP (or any Pascal
for that matter).  But there are Ada solutions to writing to the printer.  

I'm not sure about reading  from the keyword.  Easy  things can be  done by
TEXT_IO.GET[_LINE].  Single character I/O and  special character I/O may be
a bit more tricky.   Check  you Ada manuals first  before trying to  pragma
INTERFACE.

Hiya!

I was wondering if there's a way to stop a screen from scrolling and
pausing after a certain amount of line i.e 24 is printed. Furthermore allows
the screen to scroll once a key's pressed. I'm currently using gnat3.03 with
the new Ada95.

Thank you for yout time.

     The put_line above should be changed to

put(net_pay, AFT=>3,EXP=>0);
new_line;

because Float_IO (and therefore flt_io) doesn't have a put_line, only a
put.  (The new_line in the corrected code above will come from Text_IO.)

     Also, since you're not using dot notation for the packages, you
should add USE clauses to your three instantiations, like this:

package flt_io is new Float_Io(Float); use flt_io;
package int_io is new Integer_Io(Integer); use int_io;
package boolean_io is new enumeration_io(Boolean); use boolean_io;

     That should fix everything.  When you run the program and type the
number of dependents, don't forget that you're inputting a float.  E.g.,
type "3.0", not "3".  I hope this helps.

There is no Put_Line in Float_IO.

You need to add the line:

  use flt_io;

to make subprograms visible after the line which defines
flt_io. Another alternative is to use flt_io.put_line instead of
put_line.

I did not plow through the original code, but if that is the answer
for this specific problem, then the general answer is to get a
compiler which issues better error messages.

About this last point, it depends on which compiler you're using: the remark is
true for Ada 83 compilers, but Ada 95 (and thus Gnat) allows to enter an
"integer" value when a floating-point is expected: see ARM (v6.0), annex A.10.9.
In this case, typing "3" is OK...

     True.  But I assumed that the original poster was using Ada 83,
because he wrote "Text_IO" and did his own instantiations of Float_IO and
Integer_IO.  However, your point is well taken, and I probably should have
pointed that out in my post.

Easiest way to know where this is, is to look at what's in
ADA_INCLUDE_PATH.  It will have listed in it, the directory containing
the library stuff.

The trouble if you do this is that you will not know what is standard
Ada, and what are routines special to GNAT that are not part of the
language. Better to stick to the standard documentation sources (RM
and the GNAT manual. The one exception is that the GNAT hierarchy
contains routines that are definitely available for use (but are not
standard Ada).

Advising people to look in Ada_Include_Path is not helpful on many 
GNAT systems, because the library will not be in the path (on many
GNAT installations, following standard Unix practice, there is a default
directory for the standard library that is NOT explicitly in the path.

You can find it in annex A of the Ada RM (go to www.adahome.com to find
a copy), or in any good Ada text book. The basic set of library routines
is part of the language.

GNAT provides some additional library routines that are documented in the
GNAT reference manual, which is part of the distribution.

Good points, well taken.  I believed though that the poster wanted to
look at the sources (which may well be for legitimate reasons).

[UserID]

I'm currently doing Data Structures with Ada at Edith Cowan University,
in Australia and am looking for some help in writing an assignment.
the assignment has to do with stacks bounded and unbounded as wellas
counts arrays etc. if any one can helpl please let me know it would be
greatly appreciated.

Re: Help!!

[Michael F Brenner]

    > Unbounded versus bounded stacks. 

I think unbounded stacks are more useful and more fun to program. What
have you done so far?

help!

[oliver white]

I am a first year student at Edith Cowan university (Mt Lawley campus,
perth), studying for my B.Sc(software engineering) degree. Basicaly my
problem is with getting my ada compiler to work. I have downloaded
GNAT307 from a web site and have installed it as the readme file says.
The compiler is dos based, and I am using windows 95 (waiting for that
little bug everyone is telling me about to destroy months of hard work).
Anyway, the install program creates gnat307.bat which is supposed to set
it up. I run this and find "echo off" appearing at the dos prompt and
windows 95 telling me the thing is finished. Help me, I have an
assignment due on monday :( *sob*.

post a reply or email me at ojw@iinet.net.au. Thanks.

Help?

[Matthew Lawrence]

Hello to all

I have a question that I'm sure will seem incredibly simple to most of you
but I'm a first semester computer science major and it is giving me some
trouble.

In one procedure I have stored a set of records in an array.  I need to in
another procedure access individual fields of those records.  I guess I have
two main questions.

1) Can I pass the entire array from the first procedure to the second?

2) How would I access individual fields of the records that are stored in
the array?

I've scoured my textbook for any help but must be looking in the wrong
places.

I would like to be more specific but prefer not to ask program specific
questions as it is an individual assignment.

Any help will be much appreciated

Matthew Lawrence

Yes.

if Arr is the array, Arr(I) is a single array element (i.e. a single
record), so Arr(I).Component is a component of that record.

Your real problem here is that you are probably reading the
text book at the wrong level of abstraction. You will not find
something specific in the text book that answers question 2)
above, but you WILL find

a) how to access elements of an array
b) how to access fields of a record

The point is to understand that the answer to your question
is simply a matter of comprehending that the answer to a) and
b) must be composed to provide the answer to 2).

E.g. in this case

a)   use the notation array_var (subscript)
b)   use the notation record_var.record_field

Answer to your question 2

  array_var (subscript).record_field

Think of it this way, suppose Ada has 100 features of this type.
What we want in the text book is a clear description of the 100
features. It is up to you to combine them. You can't expect to
find in your text book specific help for "how do I combine
features 2, 34 and 71". A text book that provided this kind of
coverage would have to have 2**100 sections, which is a large
number :-)

I find that this inability to abstract from documentation is
one of the most common failings. It is one of the reasons
why so many people come
to depend on examples, because the examples often show (in a
very limited manner) how to combine features.

Re: Help?

[Riyaz Mansoor]

assuming all these procedures are in the same package or the public part of
another package (not likely) you'll be able to directly access the fields in
the record. if not that particular package should have procedure/functions
to access the fields of the record.

in ada u can pass almost anything into a procedure/function.

since you've already got the array, all u have to do is loop thru it till u
get the matching record. the condition would be

    record(count).field = whatever_u're_checking

i hope that's ok

Help!!

[Paul Moran]

Gday Ada Newsgroup,

My name is Paul,

I am studying Ada - Gnat95 at University. I have never programmed before....

I have this question for home work that I have little to no idea how to
do....

If you could please give me any help so that I can see exactly what you've
done it would be greatly appreciated! I imagine it is the type of question
that would take no more than 5-10 min's if you knew how to use Ada.....me, I
have been searching through my reader for hrs on end!!!

The reason I cant simply bring it into uni, is that I study externally, some
1500 klms from my campus!!

Hope you can help me as I am really getting frustrated with this subject
Thanks alot. If you cannot help, could you please recommend some one who
might be able to??

Thanks for your time and patience...

Paul

Heres the Question:

Write an Ada program for the Nordenham Booking System that calculates and
prints the price of a ticket to the Olympic games events:
            - Olympic Ceremony        abbreviated to OC
            - Women's 400m              abbreviated to CF
            - all other events              abbreviated to ETC
Each of these events has a different price:
            - OC  - $300.00
            - CF   - $450.00
            - ETC  - $155.50

The program should prompt for what type of destination is requested. It
should then read an appropriate enumerated literal indicating the desired
calculation, prompt for, and get, the number of tickets required and read an
integer value. It should than ask you for your name and read it. Finally the
result of the desired calculation should be displayed in a pleasing format
on the screen.
The program should echo print the data. The output data should be
appropriately labelled and formatted to two decimal places.

  Ch : Character;
begin

  When you find something simple seems hard to do in Ada, you must be
missing something.  When you find something hard is hard to do, there's
probably a better way in Ada.

This seems like more work than is needed. PragmARC.Get_Line from the
PragmAda Reusable Components does this (and from other
Ada.Text_IO.File_Type files as well) without repeatedly modifying an
unbounded string.

I'm having a few problems with my school ADA project.

I have to write a program which translates 10 English words to French
but when it Translates a sentence it does it in upper case instead of a
capital letter for the first letter and lower case for the rest.

Any ideas how I could get round this ?

If I were doing it, I would make a separate phase to apply the
capitalization rules for the output language.  You might want
to do the same thing for punctuation, since if you later change
the program to have the output language be Spanish, I think the
punctuation rules are different for questions.
