F1 Displays a screen for you to specify the names of files to be used by Data Build
during the conversion project. A conversion project produces a COBOL85
conversion program and converts one or more input data files.
F2 Directs Data Build to build a DDL file that defines the input and output records for
use in the COBOL85 conversion program. The DDL file is built from information
in the Source Record Descriptions file, which you previously created.
F3 Directs Data Build to create a file of conversion procedures that includes the code
to convert each input field. The conversion for each field is based on its data type
as specified in the Source Record Descriptions file.
F4 Directs Data Build to create a COBOL85 conversion program that:
1. Reads input from a file that was specified in the F1 screen.
2. Uses an input and output record structure defined by the DDL created in
step F2.
3. Converts the data using the conversion procedures created in step F3.
4. Writes the data to an output file that was specified in the F1 screen.
F5 Directs Data Build to run the COBOL85 conversion program.
