Converting yes or no to one letter strings.

[Lou <lou@xxxxxxxxxxxxxxxxxxxxxx>]

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.
