Specifying named constant values
EPL supports the use of variables in monitors. Depending on where in the monitor you declare a variable, that variable is global or local:
*Global. Variables declared in monitors and not inside actions or events are global variables. Global variables are in monitor scope.
*Local. Variables declared inside actions are local variables. Local variables are in action scope.
A variable can be of any of the primitive or reference types that are listed under Types in the EPL Reference.
Information about variables is presented in the topics below.
