I love this thread. Who'da thunk alphabets could be so much fun? FWIW: Different language, different rules - to do 'letter math', letters must be converted to their ASCII number value, add one, convert back to a letter. The set of allowed ASCII numbers is limited to (I think) 256 and 'real' letters are a subset of that collection. Going from a-z was easy. Once you hit z, you reverted character 1 to a, then looped a-z for character 2, repeat as required. There were only a couple of ways to evaluate a string's 'size'; alphabetical and length. Each comparison generated different results and one had to choose the comparison method based on the particular requirements. In order to convert a string to some numeric value, I believe I had to do it letter-by-letter and derive my own 'value' for the string which would be mostly useless. While the specific language methods differ from PHP (the language did not allow anything like 'a'++ so this particular discussion couldn't happen), it doesn't seem to me that the philosophical underpinnings are all that different - letters are special. They look and behave differently depending on the particular microscope you happen to be using. Anybody want to talk about rounding? ;-) Doug _______________________________________________________________________ This e-mail message has been sent by Kollsman, Inc. and is for the use of the intended recipients only.
