This very Disagreeable calculator will produce the integers 1 through 20.

Tabulate your response ¹, eg:
aaaaaa1aaa A
aaaaaa2aaa AA
aaaaaa3aaa AAA ...

Please press "Clear" to start², and at any time to reset the display.


Note
1. The example response table is clearly not correct!
2. If you invoked a time/date stamp please press "Clear".
3. Use your keying as efficiently as possible.

(In reply to sequences by Daniel)

On the sequences starting with AAA: AAAB and AAAC, they really should be AA.  AAA just returns to zero; AA gives the -1 you need for these, 2 and 6 respectively.
