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 Packet 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 packet of type MY_TX_PACKET.

$X = MY_TX_PACKET

# Note: Packet variables can be declared/redeclared and

# used many times.

# Declare a variable Y and change the default packet.

$Y = MY_TX_PACKET

# Template field values

{

DevAddr = 0x10

Endp = 2

}

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

$Z = Y

{

DevAddr = 0x10

Endp = 2

}

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

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

# templates.

$MY_TX_PACKET = MY_TX_PACKET

{

DevAddr = 0x10

Endp = 2

}
