You have to remember that commands like PREFIX that you type at the ] Applesoft
prompt are NOT ProDOS commands, they are BASIC.SYSTEM commands. The BASIC.SYSTEM
PREFIX command calls one of two ProDOS system calls (SET_PREFIX or GET_PREFIX)
depending on how you use it (to set or query the prefix).

Any application can be written to use the ProDOS ONLINE system call but Apple
forgot to add this as a command in BASIC.SYSTEM. You can write an external
ONLINE command for BASIC.SYSTEM and in fact someone just posted one.
