Selection parameters

You can use patterns to specify a variety of acceptable values for the accounting information fields. A pattern consists of alphanumeric characters and three special characters: an asterisk (*), a logical NOT symbol (¬), and an equal sign (=).

Use an asterisk to match any string of characters including the null string. You can use it more than once.

Use the logical NOT symbol (¬) to negate the result of a match with the pattern. You can specify it only once. The logical NOT symbol is removed from the pattern before a match is attempted. Therefore, the position of the logical NOT symbol within the pattern is not significant.

Use an equal sign (=) to indicate all groups that are at the same layer in the hierarchy as the group you specify. An equal sign can only be specified once in the pattern.

Use the equal sign only in the group field. Do not use the equal sign in conjunction with other wildcard characters. If you use the equal sign, you must specify a valid group name. The name specified is taken literally.

Note: Do not use an equal sign (=) as the first character in a pattern because it is a special character in ISPF.

Use the patterns shown in Table 1 to select accounting information.
