[ale] programming question

[Brian Schenken]

It depends.  The characters in serial numbers sometimes have a meaning - O
could mean an item was assembled on production line O, etc. so you might
have to change that logic a bit.  Assuming that the characters are all
meaningless, you'd still have a bit of work to do if you want the
alphanumeric text to increment while excluding certain characters.
