This documentation describes the Natural system variables.
Natural system variables contain information about the current Natural session, such as: the current library, the user and terminal identification; the current status of a loop processing; the current report processing status; the current date and time. They may be referenced at any point within a Natural program.
The documentation for the system variables is grouped by functions:
|
