Thanks. I'll try to start with the indexing table for each character first. Anyway do you know how to split string based on more than 1 character, for example I want to split string based on some punctuation. I have tried using tokenBasedOn, but still can not figured out how to use it for more than 1 separator.

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 :)

but maybe you could reverse the collection so as to have ($a -> 1 ... $z -> 26)

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. So 'a' and 'A' each have value 1, 'b' and 'B' each have 2, etc. Non-alphabetic characters can be considered to have value 0. The value of a word is the sum of the value of all its characters. So 'Smalltalk' has value 101 and 'abc' has value 6. A dollar word is a word whose value is 100. I want to add a method to the String class that returns all the dollar words in the string.
So for example if the input is 'SmallTalk' the result is ('SmallTlk' 'SmllTlk').
Please kindly help me guys. Really appreciate your help.
Thanks.
