If you do not have an XFD, FairCom RTG allows you to create the XDD from your COBOL source code. The XDD is generated from COBOL source code using xddgen. This command-line utility analyzes the COBOL program to determine the schema. You will specify the COBOL program file as input. A variety of other parameters allow you to specify the dialect of COBOL (ACUCOBOL, Micro Focus, IBM, etc.), source format (free or fixed), directories, and other options.
After creating the XDD, use the procedures in the section titled Storing the XDD in the Data File to prepare your data file for SQL access.
