Unload function inputs and outputs
As shown in the following figure, the unload function processes input from an area data set or an image copy data set.
Use the unload function to unload one or more areas from a DEDB in any of the available formats. For more information about available formats, see Controlling the unload file format.
The ACB of the database that is being unloaded is used to describe the input areas and is referenced by the IMSACB DD statement. The ACB of the database to be reloaded is referenced by the NEWACB DD statement and is used to describe the output files.
