Filter pattern masks

Many commands allow you to specify powerful filtering masks using extended ACS masking characters, as shown in the following table.

Note: Your installation may need to specify different masking characters to achieve the desired result if your code tables are different from the U.S.A. EBCDIC code set.

Mask	Hex	Description
`*` (Single character)	5C	Can be used before an item or after an item (or both) to designate a wildcard character position. Consider the following example: `PROD` An item is selected if the last four character end in PROD regardless of the starting characters. Using the `` character before and after an item (`ZREM`) means that item is to be selected if any character string matches `ZREM` in its name. Note: You can not use an `*` in the middle portion of a single item (except for data set names). Use the `%` character (see below) for that purpose.
`%`	6C	Denotes a single character placeholder value, which can be alphanumeric or any special character. The `%` character can be used in any position order. Consider the following example: `CRM%%ER6` An item is to be selected if it is 8 characters in length and the first three characters are `CRM` and the last three characters are `ER6`. The two middle placeholder values can be any characters.
`<`	4C	Similar to the `%` value, the `<` character denotes a placeholder value for alphabetic or national characters only. The `<` character can be used in any position order. Consider the following example: `CR<<ER*` An item is to be selected if the first two characters are `CR`, the third and fourth characters must be alphabetic or national characters, the fifth and sixth characters are `ER`, and any remaining characters are allowed.
>	6E	Similar to the `%` value, the `>` character denotes a placeholder value for only numeric characters. The `>` character can be used in any position order. Consider the following example: `CR>>ER*` An item is to be selected if the first two characters are `CR`, the third and fourth characters must be numeric, the fifth and sixth characters are `ER`, with any remaining characters allowed.
\|	4F	Denotes a multiple character placeholder value for alphanumeric characters. The \| character can be used only in the final position of the mask to represent ‘any number of alphanumeric characters.’ Consider the following example: `ABC.PROD1017.\|` An item is to be selected if the first three characters are `ABC`, followed by a period (.), followed by the characters `PROD1017`, followed by a period (.), followed by one or more alphanumeric characters.
`**` (Double asterisk)	5C5C	Allows compatibility with standard ACS and DFSMSdss filtering masks. This mask is used only for partially qualified data set names. The `` or `` characters can be used in any qualifier position to denote a wildcard node. Consider the following example: `CRFM.VER.` A data set entry is to be selected if it has at least two qualifiers and the first qualifier starts with `CRFM`, the second qualifier must end with `VER`, and any remaining qualifiers may contain any number of alphanumeric characters. Note: As with common data set name masking, any combination of ``, `**`, `%`, `<` and `>` characters can be used for the item mask value.
`!`	5A	Similar to the `%` value, the `!` character denotes a placeholder value for national characters only. The `!` character can be used in any position order. National characters are `@`, `#`, and `$`.
