Terminal Processing 7
Controlling output
3270s, OUTLPP can only be reset as a result of resetting the MODEL
parameter.
Model 204normally displays a line showing the current date in Julian date
format, the current date in mon dd format, the time in hh.mm.ss format, and
page number at the top of each page of output. For example:
91.010 JAN 10 05.15.29 PAGE 37
The page number is incremented automatically as new pages are produced.
The user can specify alternative headers as described in the Model 204 User
Language Manual.
If the user has requested a page trailer, Model 204 displays it at the bottom of
every page. Model 204 also pauses at the end of each page of output to allow
the user to cancel future output, to change the terminal paper, or to read text
that is displayed on a screen.
Production of all headers and trailers, except for the header on the first page,
can be cancelled by setting the OUTLPP parameter to zero on hard-copy
terminals. Setting OUTLPP = 0 also causes the pause at the bottom of each
page to be suppressed. Output is displayed in a steady stream. Setting the
OUTLPP parameter to -1 eliminates page counting, but it displays headers and
trailers when a NEW PAGE command causes output of a new page.
Pausing
On all terminals described in this manual, Model 204 can pause at the bottom
of the page and wait for the user to respond before continuing. If output consists
of more than a single page, Model 204 will display one page or screen, pause
at the bottom of the page or screen to await a user response, and continue
displaying output at the top of the next page or screen after the user has
requested continuation.
When Model 204 pauses at the bottom of a page while displaying output, the
user’s response depends upon the terminal being used. (A variety of responses
are described in subsequent sections.) If the user enters an input line instead
of one of the expected responses, Model 204 saves this line in most cases.
Output continues on the next page, and the saved input line is processed after
the output is completed. However, if Model 204 fills another complete page or
screen with output and once again pauses for a user response, the response
causes the saved input line to be lost. Input lines entered in this fashion are
never saved by the CICS, TSO, CMS, or INTERCOMM interfaces.
If the last line of a page is used for input, Model 204 does not pause at the
bottom of the page.
Backpaging
Model 204 supports a backpaging feature that allows the user to review
previous pages of output. This feature is very useful to users of terminals that
