10.2 Local Structure Parser Variables

You can declare a local "structure" parser variable, which is seen only inside the generation

procedure, and use it in a Send Frame instruction and field assignments.

Format

[ Local ] $var = template_or_var_name

[ Local ] $var = $variable_name

Note: The Local keyword is required if you already have a global variable with the same name.

Using this keyword explicitly instructs the script parser to declare a local variable with the same

name.

Example

Main

{

# Declare a variable X as a frame of type MY_TX_FRAME.

$X = MY_TX_FRAME

# Note: Frame variables can be declared/redeclared and used many times.

# Declare a variable Y and change the default frame.

$Y = MY_TX_FRAME

# Template field values.

{

DestAddr = 0xAABB

SrcAddr = 0xEFBE

}

# Declare a variable Z using the frame variable Y as a prototype.

$Z = Y

{

DestAddr = 0x1122

SrcAddr = 0x3344

}

Local $Z = Y # Explicitly declare a local variable.

# Declare a structure variable having the same name as one of the

# templates.

$MY_TX_FRAME = MY_TX_FRAME

{

DestAddr = 0xAABB

SrcAddr = 0xEFBE

}
