Character Lists

A character list enclosed by square brackets ( [ ] ) can contain one or more characters. CA Access Control uses these characters as positive or negative matching criteria.

A character list can be composed of one or more characters. For this type of list, CA Access Control matches any single character in the list. If the list within the brackets is preceded by a caret (^), CA Access Control matches any single character, which is not in the list.

A range is a type of character list that specifies a range of characters. CA Access Control matches all the characters in the list, inclusively. If a caret (^) precedes the list, CA Access Control excludes all the characters in the specified list. You can specify both ends of the range, or only its first or last character.

The following table describes the character lists that can be used. Remember, in this syntax, you include the square brackets. Each of the expressions ch1, ch2, and chN, stands for a single character.
