This mostly depends on the hardware, but typically home computers would boot in BASIC and <code>JSR</code> to the starting address on the disk. This means that the return address for BASIC is on top of the stack, and an <code>RTS</code> instruction will exit the program and return to BASIC, provided that execution is not inside one of the disk's subroutines.
<lang 6502>;assuming this is not a subroutine and runs inline.
