Precise language

From a discussion in the comments at TSO’s place:

>Reminds me of my System/360 days when we had to suggest to the programmers that rather than ask the operator at the console to type “1 for Yes, 2 for No”, the program should request “Y for Yes, N for No”.

>And what’s wrong with “1” for Yes and “2” for No exactly? 🙂

>One for yes and two for no is great if you have at least one position to the right of the decimal point.

>”And what’s wrong with ‘1’ for Yes and ‘2’ for No exactly?” 1thing.
