SET LP
(LP)
Sets the line-printer handler.
Format
SET LP condition
Condition
[NO]BIT8
BIT8 sets the LP handler to pass the eighth bit unaltered, but does not guarantee
the eighth bit will arrive at the output device unaltered. The following can alter
or strip the eighth bit:
• Some RT–11 utilities in ASCII mode
• Some RT–11 KMON commands, such as PRINT
• Hardware device initialization program options
• Hardware device straps
NOBIT8, the default, sets the LP handler to force the eighth bit to zero, but does
not guarantee the eighth bit will arrive at the output device as zero.
[NO]CR
CR sends carriage returns to the printer. To allow overstriking on the printer,
use this condition for any FORTRAN program that uses formatted input and
output. Use CR also for any LS11 or LP05 line printer to prevent loss of the last
line in the buffer. LP NOCR is the default mode.
NOCR, the default, prevents the system from sending carriage returns to the
printer. This setting produces a significant increase in printing speed on LP11
printers, where the line printer controller causes a line feed to perform the
functions of
RETURN
.
CSR=n
Modifies the line printer handler to use n as the Control and Status Register
(CSR) address for the line printer controller. The valid range for n is 160000 to
177570
8
. This option enables you to set a special CSR value in the line printer
handler itself, without having to modify and reassemble the handler source code.
Use this option if you have installed the line printer controller at a nonstandard
address.
[NO]CTRL
CTRL passes all characters, including nonprinting control characters, to the
printer. Use this condition to pass the bell character to the LA180 printing
