My main goal is to create a simple and easy to use language where the code can be written using Windows, Linux, Raspberry Pi etc. and then compiled for a wider range of platforms including 8-bit retro machines and WebAssembly.
The created programs would be text only, so the graphics capabilities of the target machines would not be an issue.
I don't know of any Pascal compilers that can target multiple retro machines, but I have found a couple of C compilers that should work.
As I personally dislike C syntax and it isn't the easiest language for beginners (who would hopefully eventually use this language) I would need some sort of conversion option.
Pascal is already quite close to what I'm aiming for. It would just need a few minor tweaks to become more accessible to beginners, those using screen readers or anyone that is used to BASIC.
To create an entirely new language from scratch seems like it would be a lot of wasted effort when other established languages are available.
A slightly easier option would be to modify an existing language and compiler. That would also require modifying/creating a transpiler targetting C though.
Even easier would be to create an internal or embedded language, which is an option I have only recently discovered is possible.
