Debug Commands

DN Command
If you omit BY columns, Debug determines the number of items to display on
a line.
display-format has this form:
{ IN| : }
specifies that the display-format (output) follow in the command. You must
begin display-format with an IN or a colon (:). In a DN command, a
count-format specification and a display-format specification can
appear in either order.
[ S | U ]
specifies signed or unsigned displays for octal and decimal numbers. In a
signed (S) display for a negative value, a minus sign (-) precedes the value. In
an unsigned (U) display, no sign appears. This option is ignored with other
numeric bases. The default specification is U.
display-type
specifies the format of the display. The format of display-type is:
{ A }
{ I }
{ R | N }
{ T }
{ B | %B }
{ O | %O | % }
{ D | %D | # }
{ H | %H | X }
The descriptions of these formats are:
{ IN| : } [ S | U ] display-type [ display-size ]
A displays ASCII code.
I auto-select instruction decoding based on a process type.
R | N displays RISC instruction code.
T displays TNS instruction code.
B | %B displays information in binary.
O | %O | % displays information in octal.
D | %D | # displays information in decimal.
H | %H | X displays information in hexadecimal.
