$Y = MY_STRUCT

# Change the structure variable from a hex stream.

$Y = {

11 22 33 44 55 66 77 88

}

# After the above change, the variable Y fields have the

# following values:

# Y.V1 = { 11 22 }

# Y.V2 = 0x33

# Y.V3 = 0x44

# Y.V4 = { 55 66 77 88 }

# Change $Y from the above to {AA BB CC DD 55 66 77 88} and

# add local field F6 to variable X.

$Y { V_123 : 0, 32 = { AA BB CC DD }

$Z = MY_STRUCT_2

# Attempt to copy $Y to $Z. This will NOT work and may or may not

# generate a parse error.

# If no error is generated, the parser skipped this instruction.

# (Because $Z is derived from MY_STRUCT_2 and $Y is no longer

# purely MY_STRUCT_2 with its local variables,

# this assigment is not valid).

$Z = $Y

# Copy $Y to a newly instantiated $W structure variable.

# This is legal because $W does not have a frame template

# associated with it, because it is being declared.

$W = $Y

# Change $Y from the above to

# {AA BB CC DD 55 66 77 88 00 00 00 00 FF FF}

# and add local variable V5 at offset 96 with length 16.

# Offset 64-95 is padded with zeroes.
