The d Command
d

The d command displays memory contents in hex or ASCII format.

Format

The format for the d command is:

d [-b|h|w|s|S] adr [cnt|-rreg]

where:

-b	displays the memory contents in groups of bytes.

-h	displays the memory contents in halfword groups.

-w	displays the memory contents in word groups.

-s	displays the memory contents as a null terminated string.

-S	cnt is the number of data items to be displayed.

adr	specifies the base address from which data is displayed.

cnt	specifies the number of lines displayed.

-rreg	displays the contents of memory as register reg.

Functional Description

The d command displays memory, starting at the specified address, in 
hexadecimal or ASCII format. A -b, -h, -w, or -s option, if specified, sets 
how the data is displayed. See the examples at the end of this section for 
illustration of the possible display formats.

The datasz and moresz Variables

If invoked without a -b, -h, -w, or -s option, the datasz variable sets the 
display format. Setting datasz to -b, -h, -w, or -s has the same effect as 
the command line options of the same names described in this section. The 
datasz variable does not effect any other command displays.

If invoked without cnt, the d command first displays the number of
lines specified in the environment variable moresz. The Monitor then pauses and displays the more
prompt. See the more command for commands available with the more
prompt. Also see the more command for more information on the moresz
variable.

The following example displays memory starting at 0xa0010000.

PMON d a0010000 
a0010000 bf c0 2b 00 bf c0 2b 00 bf c0 2b 00 bf c0 2b 3c ..+...+...+...+
