10.9 Using the Append Operator in Field Assignments
You can append data to fields using = + (append operator) in field assignments. Use the append
operator to generate dynamic packets and avoid restating previously assigned values. For
example, if a packet variable field SomeField
contains “01 02 03”, to add “04 05 06” you can
assign SomeField = +{04 05 06} ), rather than assigning SomeField = {01 02 03 04 05 06}.
Note: Do not confuse this operator with the += operator, or a parse error will be generated!
You can write the append operator as = + or =+ (without a space), but it is recommended to use
the space to avoid confusion with the += operator.
