The value in the white list or black list of a processor can contain special characters; this makes it possible to use pattern for value matching. The matching is done by using Visual Basic “Like” operators.
Characters in Pattern | Matches in String |
|---|---|
? | Any single character |
* | Zero or more characters |
# | Any single digit (0–9) |
[ charlist ] | Any single character in charlist |
[! charlist ] | Any single character not in charlist |
