Hi again,
Since I hadn't heard back, I've decided to send you the alternative files. Your parser won't directly handle
the Europe file, as it follows the majority of your rules, but created a different exception, which should allow more
latitude for your rules, while hopefully simplifying exceptions in the parser unit. The "%" in front of "LETTER/S" signals
direct or literal replacement much like the "-" is to "RULES". The Europe file was also rearranged slightly to group
regions together for analysis.
Thanks again and hope these help.
Steve
