POINT
• When variables are included in receive packet elements, variable parts are not
verified.
• With multiple receive packet specifications, receive data are verified with
registered receive packet information starting from information of the first
registered packet, in the registration order. Once the receive data match one of
them, the receiving process is performed and the following verification is
cancelled.
• The number of a receive packet which is matched in the verification is stored in
the control data of the dedicated instruction (CPRTCL instruction).
