Dear George,

/* vbs built-functions */
Discussion on detailed vbs features are not covered during tutorial time, it is expected that you make use of vbs built-functions as much as possible where apply.
Please pay attention to three major types of functions: mathematical, date related, and string manipulation.

/* vbs regular expression */
Regular expression is a nice feature for pattern matching; it's more elegant and effective than using simple string processing functions.

regards, Jamie
