Data definition (DD name) list
The DD name list must begin on a halfword boundary. The first two bytes contain a binary count of the number of bytes in the list (excluding the count field). Each entry in the list must occupy an 8-byte field.
The sequence of entries is:
| Entry | Standard DD name | Entry | Standard DD name |
Entry
|
Standard DD name |
|---|---|---|---|---|---|
| 1 | not applicable | 3 | not applicable | 5 | SYSIN |
| 2 | not applicable | 4 | not applicable | 6 | SYSPRINT |
| 7 | SYSPUNCH |
If you omit an applicable entry, the translator uses the standard DD name. If you use a DD name less than 8 bytes long, fill the field with blanks on the right. You can omit an entry by placing X'FF' in the first byte. You can omit entries at the end of the list entirely.
