BASIC statements end on new lines. The language does use a semicolon at the end of PRINT statements in order to omit printing a newline character at the end, but I believe that's the only use. (It's been about 20 years since I've done anything in BASIC.)

The meaning of a semicolon depends completely on the language. C and C-like languages (like Java and Rust) tend to use them to delimit the end of a statement.
