```annotated-hexdump
# Define the data
0000 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 1E 1F
0010 10 11 12 13 14 15 16 17 18 19 1A 1B
0020 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F

# Define the case. It defaults to upper, but we could also set 'lower'
/case upper

# Define the character to show for missing bytes
# This defaults to ' '
/missing ?

# Define the width of the hexdump in bytes. This defaults to 16, but you
# can use any value between 2 and 32
/width 6

# Define the address width of the hexdump in bytes. This defaults to 4, but you can
# you any value between 2 and 8
/awidth 2

# Set the base address. All addresses in the output are increased
# by this value
/baseaddress 12

# Define some highlighted regions
/highlight [0,1,2] /0
/highlight [4:7] /1

# Add some text notes to explain the highlights
/note /0 The first three bytes
/note /1 This range is contiguous

# Add a highlight, with an inline note
/highlight [20:25] /2 Not the bytes you're looking for

# Show the corresponding text, decoded using the default codepage (1252)
# You can add an optional codepage argument (e.g. /decode 1250)
/decode

# Hex dump and decoded text have a 1 character gap
# This is the default and has no effect
/decode_gap 1

# Control characters should be rendered as '.'
# This is the default, and has no effect
/decode_control .
