## ŚWARG Argument to event callback function

Obsolescent: Use ŚEVA instead.

The ŚWARG niladic system function is valid only inside a ŚWE callback function, run by APLX as the result of an event occurring in one of your windows or other objects. It is used to pass data associated with the event from an external control or server, or another APL task. See ŚEVA.
