Move
Purpose:
Moves the block of memory specified by range to the location
beginning at the specified address.
Syntax:
Mrange address
Comments:
Overlapping moves (i.e., moves where part of the block overlaps
some of the current addresses) are always performed without loss
of data. Addresses that could be overwritten are moved first. For
moves from higher to lower addresses, the sequence of events is
to first move the data beginning at the block's lowest address and
then work toward the highest. For moves from lower to higher
addresses, the sequence is to first move the data beginning at the
block's highest address and then work toward the lowest.
Note that if the addresses in the block being moved will not have
new data written to them, the data in the block before the move
will remain. The M (move) command copies the data from one
area into another, in the sequence described, and writes over the
new addresses. This action is why the sequence of the move is
important.
Example:
Suppose you type the following command:
MCS:100 110 CS:500
In response, debug would first move address CS:ll0 to CS:510,
then move CS:I0F to CS:50F, and so on until CS:I00 is moved to
CS:500. To review the results of the move, you could type the
D command, using the same address as you used with the M
command.
