F - Fill Memory With Repeated Data

Fill memory with repeated data.

Syntax:

                                       ┌──────────────────┐
                                       │                  │
                                                         │
──── F ──────── addr ────  Ln  ────────┬──  value   ──┬─┴─────
                                         └──  string  ──┘

Parameters:

addr

The address of the memory location to be changed.

An address expression may be specified.

Ln
The number (n) of bytes to fill with data.
value
A numerical byte value to be entered into memory. One or more values may be specified separated commas or blanks. These may be mixed with "string" values.
string
A character sting enclosed in quotes. Each character is treated as a byte value and entered into memory separately, no terminating 0x00 value is stored. No folding of characters to upper or lower case occurs. One or more strings may be specified separated by commas or blanks. These may be mixed with numerical values.

Results & Notes:

The list of values and strings is repeated up to the length Ln and used to fill memory at the specified address. If the fill data is shorter than the length then it is repeated, if it is longer it is truncated.

If memory is present the storage is updated otherwise an Invalid Address message is generated. If this should happen, valid storage may be paged into memory by means of the .I command..
