In the editor just press F1 and read the help text: SST - Defines the field as a substring of another field. Or go to the InfoCenter

The code below shows an example of Substring to create new fields. You can also use CONCAT to Concatenate fields. AFAIK, since you're creating a Format that's different from the Physical, you've got to define All fields that you need in the format.

I am wondering if there is a way, in DDS, to create a logical file that identifies new fields that are in fact a substring of the original physical file field. This would be similar to the OVERLAY option within the a data structure in an RPG IV program. If this is possible, please provide an example. Thanks
