User Commands
fm
The fill memory (fm) command writes data to the specified range of addresses.
Control Flags
!d (negate data flag)
ba (base address flag)
fr (follow-with-read flag)
fw (follow-with-write flag)
lo (loop flag)
qw (quadword data flag)
wa (write address flag)
Description
The fill memory command writes to a range or block of memory locations. The
range is specified by first entering the starting address, followed by the ending
address. The data to be written to the entire block can be entered by the user after the
ending address, or it can be automatically generated by the command, depending on
the state of the write address and negate data flags.
Example
In this example, the starting address (400003) will be truncated to the nearest quad-
word (400000) because the quadword data flag is on. The ending address (40004F)
is truncated to 400048 for the same reason. Therefore, the last address written with
the specified data is 400040. Similar truncations can be seen with the bm command.
