I would usually overload the operation for this using the initialization
property of enum types and the fact that they are defined to hold an
integer:

typedef enum { A = (int) 'A', B = (int) 'B', C = (int) 'C', D = (int) 'D'} CMD;

or if lexically ASCII is assumed,

typedef enum { A = (int) 'A', B, C, D } CMD;

Since B, C and D will be sequential, they will be correctly initialized.


Or is that cheating? :-)
