DFSMSrmm structured field introducers

The DFSMSrmm application programming interface (API) returns data as structured fields in an output buffer that you define. Structured fields consist of a structured field introducer (SFI) and the data. SFIs describe the type, length, and other characteristics of the data.

Table 1 shows the structured field introducers that support encryption-capable TS1120 tape drive tape drives.
