SUMMARY

The UNASSEMBLE command in the Debug utility has the syntax "U [range]" and is used to display the unassembled information contained in the specified range. For example, the command "U 0 8" displays the unassembled information in bytes 0 (zero) through 8.

The command displays incorrect results if the specified range is bytes 0 through FFFF. DEBUG displays only the unassembled representation of the byte at offset 0, rather than the bytes 0 through FFFF.
