QUIT

Terminates program execution unconditionally.

Syntax

QUIT

Description

The QUIT command terminates program execution unconditionally. Before control goes back to the operating system, all files are closed and all EXIT PROCEDURES are executed, unless a runtime error occurs during program shutdown. In this case, the ErrorLevel() function is set to 1 which is the applications's return code to the operating system.
