Description
The formatting of page headers
Valid settings of HDRCTL are (options can be summed):
| Setting | Meaning |
|---|---|
| 1 | Suppress header 0 (system header with date, time, page number). |
| 2 | Suppress the blank line that normally follows header 0 for non-request output. |
| 4 | Pause at the end of an output page. |
| 8 | Daemon threads must honor headers. (7.9 or later) |
Setting 4 of HDRCTL is valid only for the following device types:
| IODEV | Access method/device type |
|---|---|
| 29 | Remote User Language thread (line-at-a-time). |
| 37 | SNA Communications Server (formerly VTAM) 3767 and NTO - An additional line is added to each page, in addition to OUTLPP plus PGSEP, to receive a reply.
Note: The |
| 39 | IUCV User Language thread (line-at-a-time). |
| 45 | CMS console (line-at-a-time). |
Note: Use of HDRCTL 4 on Batch2 threads results in a pause being sent to BATCH2 which then responds by sending an attention back to Model 204 because a BATCH2 has no way of pausing (it is not an interactive device). An attention will usually cause an evaluating request to be terminated.
