For the sake of understanding, I clarify. This is not a fasm program. The macrolanguage of the compiler is engaged in the translation of the text and it is fasm that writes the result in the form of a hexadecimal representation to the file. Thus, the above text is a script, not a program!
To write a program for Windows OS, you need to decide whether you need a 32-bit version or a 64-bit version of the program.
Although in general, I gave the sequence of calls to the operating system functions in the post above.

Ideally I need both 32-bit and 64-bit Windows
at the very best on linux

If anyone can help, I would be very grateful.

Now I'm going home on the train and writing this (and checking) on a tablet with Linux Ubuntu installed. Running a Windows VM on it without a Bluetooth mouse is a insult to the brain. That's why I didn't check the batch script. But running fasm for testing is quite acceptable. So this script also works on Linux.
