Global variables can be accessed by any processing component from any rule, and they also can be used for data exchange between components and rules. Each global variable has its own effective interval. A variable is initialized by the initial value at the beginning of the effective interval. Within the effective interval, any processing component from any rule can read and change its current value.

The global variable list is a table with the following columns:

Type - Global variable type depending on the effective interval.

Name - Global variable name which appears in the general variable list. By default, the name appears in the Variables group.

Current - Current value of the global variable.

Default - Initial values of the global variable, bound to it on initialization at the beginning of each effective interval.

Comment - Text comment.
