Rocket 204 - Setting OUTMRL; Setting OUTCCC; Setting OUTLPP

6 Rocket Model 204 Terminal User’s Guide
Controlling output
• OUTMRL and OUTCCC parameter settings specify the maximum output
line length at a particular terminal.
• OUTLPP determines the number of lines on an output page.
OUTMRL, OUTCCC, and OUTLPP usually are set by the system manager for
each terminal in the system. For 3270s, these three parameters can be reset
as a result of resetting the MODEL parameter. MODEL allows for alternate
screen sizes within the 3270 family and is described in the Model 204
Parameter and Command Reference Manual. OUTMRL and OUTCCC can be
reset individually, independent of the MODEL parameter setting, but OUTLPP
is determined by MODEL, and can only be reset as the result of resetting the
MODEL parameter for 3270s.
Settings of the HDRCTL and TERMOPT parameters that can affect output
displays and pauses are discussed in chapters 3 through 9 of this manual,
which discuss individual types of terminals.
Note: Any attempt to enter input while a terminal is displaying a line of output
will produce unpredictable results.
Setting OUTMRL
The OUTMRL parameter specifies the maximum number of characters that
Model 204 can display on an output line at a particular terminal. Note, however,
that the number of characters specified in OUTMRL can be greater than the
physical line length of the terminal being used. If the terminal is a CRT device,
a long line wraps around and some of the characters are displayed on a second
line. If the terminal is a hard-copy device, the characters beyond the last
character on the physical line can be lost.
Setting OUTCCC
The OUTCCC parameter specifies the last available output position on the line.
When Model 204 displays a line, it uses the smaller value of OUTMRL and
OUTCCC as a line length. If the line is longer than this, a hyphen is placed in
the column position specified by OUTCCC, and the rest of the characters are
continued on subsequent lines. Any number of lines can be continued in this
fashion.
OUTCCC can be reset by the user for 3270 terminals. The reset value remains
in effect for the thread even after the user logs out.
If OUTCCC is set to zero, the value of OUTMRL is the maximum line length.
No continuation occurs, and any text beyond the value of OUTMRL is lost.
Setting OUTLPP
The OUTLPP parameter specifies the number of lines on an output page,
including headers and trailers. OUTLPP can be reset by the user. However, for
