The core principle distinguishes between the interactive interpreter environment and persistent scripting execution within the domain of computer programming. Formal definitions establish that a script is an executable file containing a sequence of instructions intended for batch processing, whereas the interpreter executes code line-by-line with an interactive prompt. The theoretical mechanism relies on specific system calls to launch the interpreter from an external command-line interface to process the script file, necessitating explicit function invocation (e.g., print) for output, unlike the automatic evaluation of expressions in the REPL.
