Maybe give you an out-of-channel text message?, but it did what you asked
for, which was to interpret that section as CODE.
Sometime, try creating a .COM file in MS-DOS that starts with
The loader in MS-DOS recognizes that as Mark Zbikowski's initials, and
will process the file as an .EXE, instead of .COM (disunirregardless of
.COM V .EXE file extension)

Yes, wouldn't it be nice if a disassembler would have the smarts to
recognize that certain bites are text, to decipher 32 bit floating point
numbers, parse and display AES DIRectory entries, notice and invert
BIG-endian V little-endian numbers, look up what any INT call is heading
for, recognize string terminator characters, and spell check any text that
it finds, . . .
