d [range]
The d command displays the contents of memory at a given address or in a range of addresses. The d command displays one or more lines, depending on the range given. Each line displays the address of the first item displayed. The command always displays at least one value. The memory display is in the format defined by a previously executed da, db, dd, or dw command. Each subsequent d (typed without parameters) displays the bytes immediately following those last displayed.
range
Specifies the block of memory to display. If you omit range, the d command displays the next byte of memory after the last one displayed. The d command must be separated by at least one space from any range value.
