System Debug Command Specifications :-Exit
ENV
# or DECIMAL
$ or HEXADECIMAL
The names may be abbreviated to a single character. The default value is %
(octal). Refer to the SET command for an alternate method of setting this
variable.
COLUMN U16 (io) rw
The current character position in the user's output buffer. The position is
advanced by the W and WCOL commands (or by the C directive in a format
specification). Refer to the W command for details.
CONSOLE_DEBUG BOOL (system) rW
If this system-wide flag is set, all processes entering the debugger for the
first time automatically have their debug I/O performed at the system
console with the system console I/O routines. Processes that have already
entered Debug and have established a debugging environment are not
affected by this variable. When this variable is set, the CONSOLE_IO
variable is set to TRUE for all processes entering Debug for the first time.
Setting CONSOLE_DEBUG is useful when doing system debugging. If global
breakpoints have been set, all of the I/O can be directed to one terminal by
setting this variable. The default value is FALSE.
This variable is not available in DAT.
CONSOLE_IO BOOL (io) rW
If set, the current process uses the system console I/O routines to perform
Debug I/O. No other processes are affected by this command. Note that
this variable has precedence over the TERM_LDEV variable. System
processes and jobs entering Debug (assuming the JOB_DEBUG environment
variable was set), has this variable set to TRUE upon entry to the
debugger. The default value is FALSE.
This variable is not available in DAT.
CPU U16 (misc) r d
The CPU number of the processor that is being examined.
CR0 U32 (nmreg) r dm
NM control register 0 (alias for RCTR). Debug uses this value while single
stepping.
CR8 - CR31 U32 (nmreg) r dm
NM control registers. These registers have the following aliases and
names (for descriptions of their usage, refer to thePA-RISC 1.1 Instruction
