INMEMO supports AM72-style save and restore area TCRT commands and provides opcodes to handle the saving and restoring of the screen used by the memo. It does not, by itself, have the ability to track or read your screen; if you don't have an AM72 or a suitable emulator (such as the Tracker), it will return a status code informing the program that it will have to handle its own restoration of the screen (assuming this is necessary or even desired.)

Note that Tracker is included within A-Shell, so save and restore is always available on that platform.
