Questions tagged [copybook]

Questions about library text as used in COBOL. This text is often used to define the structure and format of the data for records in a file. When the copybook is used as a source for a tool for data conversion, use a tag for the tool, if available; otherwise, use the 'cobol' tag and identify the tool by name. For other questions about the use or content of a copybook use the 'cobol' tag.
