10.8 Using Multipliers to Assign Field Values

You can use a "multiplier" to assign repeated data and create complex assignments. This

multiplier only works on structure variables when assigning fields.

Note: Though this multiplier uses the symbol

*, this multiplier is not the arithmetic multiplier.

Examples

Generic $X

Generic $Y

Main

{

# Use multipliers to assign field values.

# Declare a packet variable of 'structure' instance Generic with

# data FB 01 02

$TestIE = Generic { Data = { FB 01 02 } }

# Declare a 'structure' instance based on the template S2

# and change the default value for the S16 field.

$S2_Var = S2 { S16 = 2 }

Send TX_FRAME

{

Data = 10*$TestIE # Data field contains the sequence of $TestIE

# repeated 10 times:

# { FB 01 02 FB 01 02 FB 01 02 FB 01 02 FB 01

# 02 FB 01 02 FB 01 02 FB 01 02 FB 01 02 }

}

# Declare Packet Variable $X of structure Generic with data FF

$X = Generic { Data = 0xFF }

# Packet Variable $Y contains the sequence of $TestIE repeated

# three times and $X repeated two times:

# { FB 01 02 FB 01 02 FB 01 02 FF FF }

$Y { Data = 3*$TestIE + 2*$X }

Num_of_Y = 5 # Local Numeric Variable

Send TX_FRAME

{

# Example of concatenation and multiplication of structures.

# Data field contains combined payload of:

$S2_Var + $S2_Var + $X + $X + $X + $X + $X + $X + $X + $X + $X + $X

+ $X + $X + $X + $X + $Y + $Y + $Y + $Y + $Y

Data = $S2_Var*2 + 16*$X + Num_of_Y*$Y

}
