46The ''MEMOR'' instruction tells to an expansion management which ''address''
47in the target computer should be affected by the data transfer (start or
48destination address of the transfer). Optionally, it is possible to give the
49address in the expansion memorey with ''eaddress'' (offset) and bank (''bank'').

53L'istruzione ''MEMOR'' indica a una gestione di espansione quale ''indirizzo''
54nel computer di destinazione dovrebbe essere interessato dal trasferimento dati
55(indirizzo di inizio o di destinazione del trasferimento). Facoltativamente,
56è possibile fornire l'indirizzo nella memoria di espansione con ''eaddress'' (offset) e
57banco (''bank'').
