Quite realistic would be for a disassembler that couldn't recognize an
opcode to display it as
DB 1A ; Esc
DB 65 ; 'e'
DB 09
Code immediately following an unconditional JMP is likely to be data, but
could just as easily be the destination of some other JMP, so a
disassemble can't make assumptions.
A disassembler does not convert bytes into code. It merely assists YOU in
doing that.
