Dataset name masking rules
The dataset name property supports the use of mask characters. Asterisks (*) and percent signs (%) can be used to represent qualifiers or parts of qualifiers in dataset names.
Table 1 explains
the use of asterisks and percent signs in dataset name masks.
| Mask Characters | Description |
|---|---|
| * | A single asterisk by itself indicates that either one qualifier or one or more characters within a qualifier can occupy that position. An asterisk can precede or follow a set of characters. |
| ** | A double asterisk indicates that zero or more qualifiers can occupy that position. A double asterisk cannot precede or follow any characters; it must be preceded or followed by either a period or a blank. |
| % | A single percent sign by itself indicates that exactly one alphanumeric or national character can occupy that position. |
| %% | One to eight percent signs can be specified in each qualifier. |
