The Process tab is a type-specific tab where processing instructions are stored in AE's scripting language.
Object: Notification
Object class: Executable object
Object type
(short name): CALL
The script is either processed at notification activation or start. This point in time depends on the setting "Generate at runtime" which can be defined in the Attributes tab.
A notification's script cannot contain JCL lines.
