The Filter Search for Datasets feature in ISPF allows users to search for datasets on the mainframe using patterns or filters. By applying wildcards like * and %, users can retrieve a list of datasets that match specific naming conventions or high-level qualifiers (HLQs).

Navigation - Option 3.4 (Data Set List Utility) from ISPF Primary Option Menu (ISPF Home Menu).

Key Features -

• Wildcard Support: Use wildcards like:
  • * - to match multiple characters. e.g., MATEPK.*
  • % - to match single character. e.g., MATEPK.COBOL.NEWPS%
• Search by High-Level Qualifier (HLQ): Filter datasets based on their HLQ to narrow down results. e.g., MATEPK.* lists all datasets starting with MATEPK.
• Refined Searches: Combine multiple wildcards to refine the search criteria. e.g., MATEPK.TEST.* lists all datasets under MATEPK.TEST.
