Project "Comal80 compiler syntax"
Development of the Comal80 syntax with examples of Comal80 source code.
The Comal80 compiler / transpiler will be created with help of Comal80 code collected from the internet,
and I will add Pascal like objects to the Comal80. I will not recreate a clone of the Comal80 from the 80s,
but many commands are like old version from 1980s.
In the first many development versions of Comal80, I need to get help from Python and C++.
In the future it would be great if I could create new versions of Comal80 with Comal80.
My Comal80 will translate into Python and C++, and then the children can work
with there Python and C++ version of there development project.
From Python and C++ you will be able to create binary code for your device and operating system.
My syntax creation will try to get as much old 1980s code into my Comal80 project as I can find on the Internet.
Then the missing Comal80 commands will borrow from Basic and Pascal.
Then I will add Object Pascal like code for the object oriented development code added to this Comal80 project.
Thru object classes I will add predefined classes with reduced functionality to everything from
GUI, 3D graphics, video, MIDI, audio, network, encryption, and more. Children will learn to write
all code in an text editor. No graphical elements to be moved around while write the Comal80 code.
Children learn to write Comal80 code, Run Debug Test the code, and switch back to there Comal80 code.
Threads, half baked code from backend operating systems, libaries, frameworks will all be hidden away from children.
If children wants more functionality, then they can work with the generated Python and C++ code later.
In the 1980s computers would barely nothing but write text on the screen, draw simple 2D graphics in a few colors,
and make a beep in the speaker. Today computers can do much more. This is reflected with this Comal80 compiler.
While simple Comal80 code with recreate the old limited days of what computers could to back then. Combined With
object oriented programming will add all the functionality that computers can today.
Workflow by the child (and adults):
The child write the Comal80 code, and test the code while give the command "run".
The transpiler then transpile the Comal80 to "temporary intermediate development language.
Then Transpile the "temporary intermediate development language" to C++ and Pascal.
If an error happens. then the error is descriped to the child in the Comal80 IDE (Integreted Development Enviroment),
typically a simple text editor.
My intermediate language is a combination of static objects, well defined variables, predefined modules and objects, easy syntax
reading for humans. This should help make the next compilation to Python or C++ more easy and secure.
There are NO focus on speed. All focus is on readability and comprehensibility.
Children don't know how to write secure and safe code. So this transpilation can help with this task.
Have fun developing and programming no matter sex and age.

Removed from my Comal80 version
All Goto line number are removed. Line numbers for every Comal80 line are removed also.
This is done because it makes a very bad programming behavior, and very outdated and lowlevel use case.
The use of labels and goto label is also removed. Please use newer methods for development.
