8.8 Fill Memory F

Format:

F StartAddress EndAddress|+Length ByteString|CharacterString

FL StartAddress EndAddress|+Length ByteString|CharacterString

To fill memory with a repeating sequence of bytes, the start address must be explicitly stated (an

asterisk will not do). Either the end address, or a length must be specified, followed by the bytes or

character string to be placed in memory. Character strings must be delimited by matching pairs of

single or double quotation marks. The number of bytes or characters in the string is limited to 32. Byte

strings must have two characters per byte.

The F form writes to MCU-controlled memory, FL writes only to local memory.

Examples:

F 8000 800F 01 Fills MCU controlled memory from address $8000 through

$800F with the byte $01

F 8000 800F 414143 Fills MCU controlled memory from address $8000 through

$800F with the byte sequence $41, $42 $43 repeated as often

as will fit.

FL 8000 +F 414243 As preceding example, but only fills Xplor8 local memory.

FL 8000 801F 'DEF' Fills local memory from $8000 to $801F with the repeating

sequence of bytes $44, $45, $46.

To fill memory with a single instance of a byte string or character string, the start and end addresses

may be entered as the same value. Memory is then filled with one copy of the byte string, or ASCII

bytes corresponding to the given character string, starting at StartAddress; as in the following

examples:

F 8000 8000 "Xplor8" Fills MCU controlled memory from address $8000 through

$8006 with the bytes $4A, $42, $75, $67, $31, $31.

F 8000 +0 'Xplor8' Identical with previous example.

F 8000 +0 4A4275673131 Identical in result with the previous example (bytes specified

directly, rather than as a character string)

The 'FL' form of this command may be used to fill memory anywhere in the 64 KB address space, but

the 'F' form will fail if the destination is not covered by one of the address ranges specified in

Settings>Memory.
