Ada == Pascal?

Ada == Pascal?

[bjgreene]

This may be something that has been asked before, but forgive me, I just
found this newsgroup recently. My question: Is Ada similar to Pascal?
The reason I ask is that I have to take a class that may require me to
know Ada. I've taken Pascal, so am I allright, then?

Thanx

P.S. Is Ada some sort of military/nasa code or something?

First, we should refer you to www.adahome.com, where you will find all sorts
of information about Ada 95, the language you will be learning. It is indeed
based on Pascal, in a general sort of way, but you need to study the language
to start coding in it. I have taught CS 2 to students who learned Pascal in
CS 1 and found that they could adapt fast. There are some online tutorials
that are referenced from adahome that you will find useful. Also, you can
download free software versions of Ada 95 compilers (GNAT) from many sites,
including cs.nyu.edu (directories pub/gnat).

Ada is a programming language. It is used in many fields. It was developed
originally under the auspices of the department of defense, and much DoD
code uses Ada, but it was a very open development, and Ada is also used in
many commercial applicatoins (for example the Boeing 777 is an all Ada
plane, and the Channel Tunnel signalling system is written in Ada -- you
will find more examples at adahome).

I would say that you're probably in good shape for learning Ada.

Ada and Pascal source code looks much the same (a bit more words in Ada 
though :-),�but Ada includes both posibilities and limitations not known
in Pascal.

If you want a soft introduction to Ada, you should start out with the Lovelace
tutorial (availiable at Ada Home <URL:http://www.adahome.com/>).

The old version of Ada (usually known as "Ada 83") was developed _for_ the
Department of Defence, U.S.A. - The present version of Ada (sometimes called
"Ada 95") was developed as an international standard.

I suppose the answer to the question is; "it was!"

Ada is less similar to Pascal than C++ to C :-)

Unfortunately Programming in Pascal.

That's not quite right. Ada 83 was also an international standard. The
DoD helped fund the development work, but it was not developed *for* the
DoD.

Actually the 83 of 1983 comes from the date of the ANSI standard, some
people like to tall the language Ada 87 to date it from the ISO standard.
For Ada 95, the development of the two standards was syncrhonized.

As is the Ariane 5 Inertial Reference System, but don't let that put

Sure. And TeX is similar to C because it uses curly braces for delimiting
scopes and has case-sensitive identifiers. :) Ada is nothing like Pascal 
in spite of some superficial syntactic similarities.  I've been asking C
programmers what they think of Ada; a common misconception is that it is
derived from Pascal, and therefore suffers from its drawbacks.  The comparison
to Modula 3 is perhaps more benign, but don't mention the P word!

It's a very nice tutorial.

Re: Ada == Pascal?

[TConiam]

Yes, Ada is similar to Pascal, and also Modula 3.  In addition, Ada's
object oriented, has multitasking built-in to the language, exception
handling, and many other wonderful features.

If your interested you should look at the AdaHome website at     
http://www.adahome.com/

The Lovelace tutorial will give you a good overview.

Ada was originally sponsored by the U.S. Department of Defense as a
standard language to replace the hundreds of different languages that used
to be used.  It is now over 14 years old and an international standard. 
It is used all over the world for many diverse purposes.  (see AdaHome for
a short list)

Good Luck,

I certainly wish Pascal was more like Ada! The similarities are mostly
superficial. I've been doing a fair amount of work in Delphi 2 (which uses
Borland's Object Pascal 7) and I'm constantly wishing Borland had used Ada
95... Or that someone would come out with an Ada 95 product similar to
Delphi...

Agreed.

     Well, I don't know how "similar" it is, but you certainly ought to
take a look at ObjectAda from Aonix (http://www.aonix.com).  I have
no financial interest in either product, but ObjectAda does have some
similarities to Delphi 2, and it certainly implements a much better
programming language!

Let's hope Object Ada will follow that path... but it's still far far
behind in user-friendliness, speed and Windows-95 integration.
