3.10.1 SYSTEM Class Usage

OBJECT SYS[SYSTEM];
SYS.INIT();

The SYSTEM class contains a set of procedures which form a (more or less) portable interface to the operating system. Most procedures have the same names and functions as Unix system calls. Some functions may be unavailable on non-Unix systems.

The SYSTEM class must be initialized using SYS.INIT and shut down by calling SYS.FINI.

SYSTEM does not contain any variables. Therefore, it is sufficient to create a single instance per module.
