Terminate program processing
QUIT | CANCEL*
QUIT and CANCEL both terminate program processing, close all open files, and return control to the operating system. Each of these commands can be used from anywhere in a program system. A RETURN executed at the highest level procedure or a BREAK, with no pending SEQUENCE, also QUITs the program.
. Return code: When a Harbour program terminates, the return code is set to 1 if the process ends with a fatal error. If the process ends normally, the return code is set to zero or the last ERRORLEVEL() set in the program.
. This example uses QUIT in a dialog box: IF DialogYesNo(10, 10, "Quit to DOS", "BG+/B,B/W", 2) QUIT ENDIF RETURN
BEGIN SEQUENCE, ERRORLEVEL(), RETURN
