Using the Fill
command
Fill
Purpose:
Fills the addresses in the specified range with the values in the
specified list.
Syntax:
Frange list
Comments:
If the range contains more bytes than the number of values in the
list, the list will be used repeatedly until all bytes in the range
are filled.
If the list contains more values than the number of bytes in
the range, the extra values in the list are ignored. If any of the
memory in the range is not valid (bad or nonexistent), the error
will occur in all succeeding locations.
Example:
Suppose you type the following command:
F048A:100 L 100 42 45 52 54 41
Debug would now fill memory locations 04BA:IOO through ..
04BA:IFF with the bytes specified. The five values would then be L
repeated until all the IOOH bytes were filled.
