I have two to three files with me for a project of tic tak toe, it has multiple classes, do I run with different files or run it in a single file, if it's multiple files how Do I run them
If your project consists of multiple .jack files, then you need to compile all of them into corresponding .vm files. Those should then be placed in a single directory, along with the author-supplied .vm files for the operating system libraries. The VM Emulator should then be able to execute them (assuming they have no errors).
As I've explained in another post previously:
You have to load the respective folder with all the .VM files into the VM emulator, and not a specific file.
