How to Use Job Control Standards › Masks

Masks

The Standards Selection and Standards Rule Definition panels allow you to use masks (also called generics or wildcards). Masks allow you to match one or more selected characters. A mask is an asterisk (*) for matching a string of any number of characters or a question mark (?) for matching any single character (only one). For example:

• Specifying TEST*1 displays all items beginning with TEST and ending with 1 (for example, TESTDIR1, TESTD1, TESTPRD1, TESTP1).
• Specifying TEST* displays all items beginning with TEST (for example, TESTDATA, TESTDIR1, TESTD1, TESTPRO, TESTPROD, TESTPRD1, TESTP1).
• Specifying TEST?1 displays all six-character names beginning with TEST and ending with 1 (for example, TESTD1, TESTP1).

In some cases, using masks results in the matching of more than one name. Whenever this happens in CA JCLCheck, a directory of all the names that match the user-entered name is displayed, and you are asked to choose from the directory.
