@english
 
Define a bank of memory named ''id'', starting from ''address'' 
and of type ''type''. Optionally, fill the bank of memory with static 
data coming from a specific ''filename''.
 
Available ''type'': ''CODE'' for executable code (binary), ''VARIABLES'' 
for program's variables, ''TEMPORARY'' for temporary variables and
''DATA'' for unspecified data.
 
If ''id'' is missing, the bank will have an unique name.
If ''type'' is missing, the default type is ''DATA''.
If ''filename'' is missing, the default is a simply memory reservation.
 
@italian
 
Definisce un banco di memoria denominata ''id'', che inizia da ''address''
e di tipo ''type''. Facoltativamente, riempie il banco di memoria con dati statici
da un ''filename'' specificato.
 
Valori di''type'' accettabili: ''CODE'' per codice eseguibile (binario), ''VARIABLES''
per variabili di programma, ''TEMPORARY'' per variabili temporanee e ''DATA'' per dati non specificati.
 
Se ''id'' manca, la banca avrà un nome univoco.
Se ''type'' manca, il tipo predefinito è ''DATA''.
Se ''filename'' manca, il valore predefinito è una semplice prenotazione di memoria.
