Re: Add to Character Value

Do you need to be able to choose an arbitrary letter, add an arbitrary 
number of letters, and get a result?  If so, Booth's idea is probably the 
best.  On the other hand, if you only need to be able to cycle through 
them in order, you can use an array and a for loop.  Either way you are 
likely going to want to use an array (as others have suggested).

Due to the way that computers represent characters, this is not always 
easy to do.  Since everything in a (non-quantum) computer is represented 
in bits, you have to have a standard way of determining how to encode 'A' 
or 'B' (as well as a way of encoding 'a' and 'b', which is different than 
'A' and 'B').  System i uses EBCDIC, which has multiple code pages, each 
of which could have a different .  I'm guessing your default codepage is 
37, since you seem to be located in Ontario.  Code page 37 does not define 
the sequence A-Z in numerical order (see 
http://en.wikipedia.org/wiki/EBCDIC_037), so doing math with the binary 
representations is out.  One of the array methods is better anyway, 
because it is consistent across different character representations.

Hope this helps,
Adam

Does anyone know of a method to increment a character value . For
instance I want to increase the value 'A' to be the value 'B'.
