Type SEQL=filename in the CATEGORY field of the Printing Mission Definition screen, where filename is the name (maximum length: 15 characters) of the target dataset.

The exit program appends the output at the end of the existing file (DISP=MOD).

This method ignores the default parameters of Exit CTDX005 and utilizes the characteristics of the existing file, allowing you the flexibility in specifying file characteristics. If the file does not exist, a new file is created (DISP=NEW) utilizing the macro default parameters (as in method above).

If you want to write the bundle to a GDG dataset, perform the following steps:

1. Create a corresponding generation data group (GDG) through IDCAMS utility.
2. In the CATEGORY field of the Printing Mission Definition, specify 'SEQL=GDG-name(+1)', where 'GDG-name' is the name of the generation data group.
