D - Display Memory

Display a range of memory from a given address.

Syntax:

───┬─ D  ──┬───┬──────────────────┬───────────────────────────
     ├─ DA ──┤   └── addr ──┬───────┤
     ├─ DB ──┤              └─ Ln ──┘
     ├─ DW ──┤
     └─ DD ──┘

Parameters:

• default)
  Display memory using the current display format. When the user breaks into the Kernel Debugger the current format is set to Byte display. If the user subsequently executes a DW, DA or DD command then the current format is set to words, ASCII or double-words, respectively. Byte format default may be restored by using DB.
  A
  Force memory to be displayed in ASCII format and set the current display format to ASCII. The display is terminated as soon as the first null byte (0x00) is reached or the length specification is reached.

  Note: The current display address is not updated when in ASCII format.

  B
  Force memory to be displayed in Byte format and set the current display format to Byte.
  W
  Force memory to be displayed in Word format and set the current display format to Word.
  D
  Force memory to be displayed in Double-word format and set the current display format to Double-word.
  addr
  The address of the memory location to display. When the user breaks into the Kernel Debugger this defaults the current DS selector, offset 0. If a display command other than DA is executed then the current display address is updated to the last displayed address +1.

  An address expression may be specified.

  Ln
  The number of bytes, words or double-words to display, depending upon the current display format. If not specified this defaults to 128 bytes, 64 words and 32 double-words respectively.

  Results & Notes:

  Memory is displayed according to the selected display format providing the address is valid. If it is not, but the address represents pageable storage then this may be paged in to memory using the .I command.

  The following examples show output in the four different formats. ASCIIformat :
