I have Gnat Studio but I can't do anything at all unless I create a Project (whatever that is). Even then, I can't write and run Hello_World unless I call it Main. The concept of an IDE where I can step through a program checking changes in variablevalues as I go seems to have vanished.
In short, I am lost and I can't find any material to help me find my way.

That concept is called debugger. GDB for GCC (GNAT Ada is based in GDB).
GDB never ever really worked except for little exercises. It still does
not. So, forget about it.
In short, I am lost and I can't find any material to help me find my way.The project file is 3-liner:
----------------hello_world.gpr----->
project Hello_World is
for Main use ("hello_world.adb");
end Hello_World;
<------------------------------------
No, you do not need main to be Main:
---hello_world.adb----------------->
with Ada.Text_IO; use Ada.Text_IO;
procedure Hello_World is
begin
Put_Line ("Hello world!");
end Hello_World;
<----------------------------------
You still can compile and build without projects. But projects are much
more comfortable.

Until you get to programs with a lot of tasking and/or interrupts, most
are "little exercises". Do not forget about using a debugger (and, realistically, GDB is it for GNAT).
I want to get back to doing some Ada programming and I am suddenly confronted with a whole new new Adaverse.

I'd appreciate some help. Perhaps there is a forum I cannot find for beginner Ada programmers. Perhaps there is a tutorial or a text I can download. Everything I can find is written for people with CS Degrees that are not 30 years old and whoalready know everything about this new world. What I really need, I think, is _*Ada Programming in Gnat Studio for Dummies*_. 😖
You missed the point, Dmitry. Showing me the code for Hello_World does not show me how to create the program using Gnat Studio.
Firstly, I do not understand the concept of a _Project_.
Until a couple of days ago I had never heard the term in reference to Ada Programming.
Secondly, I can write Hello_World.adb and have it included in my 'Project', I can even build it, but the only thing that will run is _Main_.
I cannot find any documentation about Studio which explains something as simple as the creation of Hello_World.exe. Can you do that in Studio or is it purely ornamental?
Thirdly, I was never a good enough programmer to be able to write programs without bugs. Perhaps you have reached that exalted stage but I certainly have not. Therefore I have a need to debug. How do I do that?

You can start GNAT Studio with a "default project". This lets you use it as an LSE.
Okay - you can use GDB within Studio. Great, but first I have to write a program.Gnat Studio installed.
Please ...
Assume: I am an Elementary School kid brought up by his Grandparents who are still struggling to control an abacus. Assume I know absolutely nothing at all about programming. Assume that I do not speak Geek! Assume that there is access to a PC with
Now: Teach me how to write "Hello_World" using Studio from scratch right up to where I have 'hello_world.exe' and can run it. That'll be great! Then I'll have something to tell Grandma about. :)

You might also find that the new alire way
will easily give you what you want but maybe
also more than you want.
You can get a hello world open in gnat studio
with two? commands though.

For myself, I have two more questions:

the problem arises when running gprconfig (all the Alire-provided
releases were built against a later Xcode (Google suggests 11.4 or
later??) which does provide this symbol). I dare say it'd happen running
the compiler too.
Only suggestion: install one of my builds, set it on your PATH, run alr toolchain --select & choose the 'gnat_external' line for the
compiler. Alire then chooses a compatible gprbuild.
11.2.0 at Github: https://github.com/simonjwright/distributing-gcc/releases/tag/gcc-11.2.0-native

I cloned 12.1.0 from Github then tried .doinstall in the native directory.
It gets to Do you want to proceed with installation but when I respond

"native directory"?
I see that the README at the link above (in fact like most of my
READMEs) might be thought to be less than clear; perhaps the very first
thing should be the Install section. It says
Download the binary .pkg. It's not signed, so don't double-click on
it; instead, right-click on it and Open. Accept the warning. You will
be guided through the installation.
It should also say that "the binary .pkg" is to be found by scrolling to
the bottom of the page.

I confused the issue as I'm only used to downloading programs from git's " code" page.
I had no problems following your instructions above which resulted in an easy installation.
I'm currently using the 2019 version of gps for development but am investigating alr.

Hmm, programs are created by typing them in an editor...
Firstly, I do not understand the concept of a _Project_.
Project is an executable or shared/static library.
Until a couple of days ago I had never heard the term in reference to Ada Programming.
It always existed. E.g. Ada 83 Reference Manual called it "the program library". See ARM 83 (10.4)

No, I provided the project file where the main procedure is called Hello_World.

Which is literally not "project", although it is a similar concept.
"Project" is now a common term in many software tools.
Back in late 90's ObjecAda had projects. The project file had extension literally *.prj....and still has, by the way :-).
