如何将这段可执行的伪代码翻译成 ABAP？

phone_numbers = { 
    'hans': '++498912345', 
    'peter': '++492169837', 
    'alice': '++6720915', 
} 
 
# access 
print (phone_numbers['hans']) 
 
# add 
phone_numbers['bernd']='++3912345' 
 
# update 
phone_numbers['bernd']='++123456' 
 
if 'alice' in phone_numbers: 
    print('Yes, alice is known') 
 
# all entries 
for name, number in phone_numbers.items(): 
    print(name, number) 

请您参考如下方法:

那么，下面的解决方案怎么样？
