System Debug Command Specifications :-Exit
ENV
system rW CONSOLE_DEBUG : BOOL (Debug only)
system rW DYING_DEBUG : BOOL (Debug only)
system rW JOB_DEBUG : BOOL (Debug only)
state - process state
The
state variables consist of all NMREG, CMREG, and FPREG variables.
The Environment Variables - Sorted Alphabetically
The following table lists all predefined environment variables. Each variable description
displays on the first line the variable name and type, group name in parentheses, and
access rights, for example:
name TYPE (group) access [*]
Environment variable description
Those variables flagged with a "*" have their value reset to their default value if the SET
DEFAULT command is issued.
ARG0 - ARG3 U32 (nmreg) r dm
NM argument registers. These registers are used by the language
compilers for parameter passing. (Alias for R26 - R23)
AUTOIGNORE BOOL (cmd) rw *
Setting AUTOIGNORE is equivalent to using the IGNORE LOUD command
before every command. When AUTOIGNORE is set, System Debug ignores
errors (that is, the ERROR variable contains a negative value). Among other
things, this means that System Debug continues processing USE files,
macros, and looping constructs even though an error occurs while doing so.
(Refer to the IGNORE command.) The default for this variable is FALSE.
AUTOREPEAT BOOL (cmd) rw
Controls the automatic repetition of the last command whenever a lone
carriage return is entered. Setting AUTOREPEAT allows repetitive
operations (such as single stepping or PF) to be automatically executed by
pressing
Return. This variable may also be altered with the SET CRON and
SET CROFF commands. The default value for the AUTOREPEAT variable is
FALSE.
CCODE STR (misc) rW
Condition code. This value is captured on entry to Debug. It is restored
when the debugger resumes the process. Since Debug itself causes the
condition code for the process to change, it is necessary to cache the
original value. The following string literals are valid: "CCE", "CCG",
"CCL".
CCR U16 (nmreg) r dM
NM coprocessor configuration register. (Alias for CR10)
CHANGES STR (win) rw
Selects the type of video enhancement used to flag window values modified
