How can I use shell to view multiple versions?

[勇胡]

Hello,

I created a table named 'score', and I issue put command twice:

put 'score','tom','course:math','1.2'
put 'score','tom','course:math','1.3'

Now the cell has two data versions, I want to read these two versions, so I
issue a command,

get 'score', 'tom', {COLUMN=>'course:math',VERSION=>2}

But I can only get the newest data version 1.3, if I also want to see the
previous value, how can I do this?

By the way, I didn't change the version value when I created the table.

Thanks

Yong
