Description Assigns the value of the right operand to the invoking object.
The left operand is the invoking object. Then one can be used interchangeably with the other. Note that assignment is different from creating two phases using the same input values. Loading p1 into a process and later unloading p1 from the same process is a valid operation. Loading p1 into a process and later unloading p2 from the same process, as if they were the same phase, is invalid.
