Populate and Decode Buffers with Copybooks

Use Populate from source to build a request buffer from COBOL copybooks. Select source by listing dataset members, searching members, or uploading local .cbl or .cpy files.

CoreIQ parses fields, extracts current values by offset and PIC definition, and opens the Field Value Editor. Edit values, review validation, then select Populate to apply them to the buffer.

After a response, select Associate source to decode it with the same source-selection flow. Response values are read-only. You can then use Confirm Match—when Hub is configured—to package the program and copybooks as an integration asset in a selected Hub module.
