Debug: f (fill)
Fills addresses in the specified memory area with values you specify.
Syntax
f range list
Parameters
range : Required. Specifies the starting and ending addresses, or the starting address and length, of the memory area you want to fill.
list : Required. Specifies the data you want to enter.
?: Displays a list of debug subcommands.
Remarks
| • | Windows XP does not use this command. It is accepted only for compatibility with MS-DOS files. |
| • | Specifying valid range entries Use range with a debug subcommand to specify a range of memory. You can choose one of the following formats for range: a starting address and an ending address, or a starting address and the length (denoted by l) of the range. For example, both of the following syntaxes specify a 16-byte range beginning at CS:100: cs:100 10f cs:100 l 10 |
| • | Specifying data You can specify data in either hexadecimal or ASCII format. Any data you previously stored at the specified address is lost. |
| • | Using list List can consist of hexadecimal numbers or a string enclosed in quotation marks (that is, "string"). |
Examples
To fill memory locations 04BA:100 through 04BA:1FF with five specific values (for example, 42, 45, 52, 54, 41) and repeat the five values until Debug.exe fills all of the 100h bytes, type:
f04ba:100l100 42 45 52 54 41
