Description

The formatting of page headers

Valid settings of HDRCTL are (options can be summed):

SettingMeaning
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:

IODEVAccess method/device type
29Remote 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 IODEV=37 setting is no longer supported as of Model 204 version 7.6.

39IUCV User Language thread (line-at-a-time).
45CMS 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.
