VAR   PARAMETERS: <name of variable> <name of field> <initial value> ("autoset"| ["static"] )
Command creates the new variable <name of variable> or reinitializes the old one if some variable of the same name is already exist. The newly created variable will have the same value's type as <name of field>. This command also sets the <initial value> for variable. Variable's value is stored separately from packet's buffer. The "autoset" type of variable indicates that the variable will be initialized by received packet (while using WAIT   PARAMETERS: {accept | drop | any }
