$X = { 11 AA BB CC DD 22 33 44 BE EF BE EF }
# After the above change, the variable X fields have the
# following values:
# X.F1 = 0x11
# X.F2 = { AA BB CC DD }
# X.F3 = { 22 33 44 }
# X.F4 = empty
# X.F5 = { BE EF BE EF }
# Change $X from the above to
# {11 AA BB CC DD 22 33 44 BE F0 0D F0 0D}
# and add local field F6 to variable X.
# The variable length fields F3 & F4 are treated as empty
# and F5 is treated as having offset 40-71,
# hence F6 occupies offset 72-103.
