System Debug Command Specifications :-Exit
ENV
amounts of data to a list file so that you do not see it on your screen. The
default for this variable is TRUE.
TERM_PAGING BOOL (io) rw *
If this variable is set, all output is paged. That is, after each full screen of
output, System Debug pauses. At that point the user is prompted with the
question "MORE?". Any response that does not begin with the letter "Y" or
"y" will cause the user to be returned to the System Debug prompt (any
pending output is flushed). This variable may also be set with the SET
MOREON/SET MOREOFF commands. The default value is FALSE.
TERM_WIDTH U16 (io) rw *
This is the number of characters to print per line. The default is set at 79.
Any output line longer than this value is split with the remainder placed
on the next line.
TIME STR (misc) r
The current time of day in the format: "5:25 PM".
TR0 - TR7 U32 (n*eg) r dM
NM "temp" registers (alias for CR24..CR31).
TRACE_FUNC U16 (cmd) rw
Setting this variable allows you to observe function calls and their
parameters. The current values and meanings are:
0 Trace is off.
1 Trace EXIT from functions.
2 Trace ENTRY and EXIT from functions.
3 Trace function PARAMETERS as well as ENTRY and EXIT.
TRUE BOOL (const) r
The constant "TRUE".
USER_REG_WIDTH S32 (misc) rw
Determines the number of register bits the user sees with the debugger.
This will affect the register display window, the output from the DR
command, and the sizes (types) of the register ENV variables. May be
either 32 or 64, but 64 bits are displayed or returned ONLY when a 64-bit
state is available. (That is, only when ENV PHYS_REG_WIDTH is also
64.)
VARS U16 (limits) rw
The VARS limit determines the maximum number of variables that can be
defined by the VAR command. The VARS limit must be set (changed from
the default) before the first variable is defined. The VARS limit is
automatically increased to the nearest prime number. The combined sum
of the VARS and VARS_LOC limits must be less than or equal to the value of
VARS_LIMIT.
