a. All words that end in "gry".

	gry$
	
b. All 5 letter words that start with 'c' and end in 'h'. (Good for crosswords!)

	^c...h$

c. All words in which the letters are in alphabetical order.

	^a*b*c*d*e*f*g*h*i*j*k*l*m*n*o*p*q*r*s*t*v*w*x*y*z*$

d. As c. but which are words which have no repeated letters and are at least 5 letters long.

   one way to do this is to pass the dictionary through
   
	^a?b?c?d?e?f?g?h?i?j?k?l?m?n?o?p?q?r?s?t?v?w?x?y?z?$
   
   then filter the output through

	^.....+$
