Syntax:
USE := <real expression>);It is used to define the quantity of resource to be used for a message.
The instruction assigns the value of <real expression> to
the field USE of the actually processed message. When the
message is processed by a R type node, the message will try
to use that quantity of resource. The value of the USE field
can be changed any number of times during a simulation run.
This instruction can be used in nodes of any type.
Example:
Warehouse (R) :: IF BoxSize = Large THEN USE := 4 ELSE USE := 1.5;
