MM
mm
– Memory modify (auto-incrementing).
The
mm
is a method to interactively modify memory contents. It will display the address and current
contents and then prompt for user input. If you enter a legal hexadecimal number, this new value will be
written to the address. Then the next address will be prompted. If you don't enter any value and just press
ENTER, then the contents of this address will remain unchanged. The command stops as soon as you enter
any data that is not a hex number (like .):
=> mm 100000
00100000: 27051956 ? 0
00100004: 50504342 ? AABBCCDD

Again this command can be used with the type extensions .l, .w and .b :
