125.  	 * characters or letters, because that limits us to 26 roles.
126.  	 * They are not booleans, because someday someone may need a neuter

128.  	 * hasn't yet specified that particular value.	If you determine

130.  	 * appropriate random value; if you just left the negative value,
131.  	 * the user would be asked again!
132.  	 *
133.  	 * These variables are stored here because the u structure is
134.  	 * cleared during character initialization, and because the

137.  	 * new and restored games.
