Hi everyone,

Is it possible to convert a boolean yes or no field to hold a one letter string? For example, the strings: 's' 'f' 'p' 'e'

To start off, I just need to convert true to 's'. false will have to be manually changed to 'f' or 'p' or 'e' as appropriate.

Why not an enum field?:

I thought enum was Considered Harmful because of the difficulty in altering the enums?


The difficulty is removing a value:

Otherwise I see equal difficulty in pretending that s, f, p and e are a boolean choice.
