The Rebuild function can be used for rebuilding index sequential files only. To rebuild other file formats, use the file conversion function with identical settings for the input and output files.

Note: If you are using a profile file, as described above, any offsets you define in the Prime-key field start at 1. However, if you use the GUI version of the Data File Converter, key offsets start at zero from the Key Information dialog box. To find out more about the Data File Converter, see the chapter Converting Data Files.
