Hi, As a start you can do:
alphabet := $a to: $z. coll indexOf: $c returns 4 to have both upper and lower case: alphabet indexOf: yourCaracter asLowercase then you iterate on your string collection and add each result... not sure about the $ word, but it could be once you detect the sum to be 100... hth :) Cédrick but maybe you could reverse the collection so as to have ($a -> 1 ... $z -> 26) 2008/9/24 Alex Chi <[EMAIL PROTECTED]>: > Hi guys, > > I am just beginner in Smaltalk and I have some problem with collection in > smalltalk. > For this problem I have to define the value of an alphabetic character based > on its location in the alphabet.
