This configuration variable applies only when running in HP COBOL compatibility mode (with the -Cp compiler option). The QUIT_ON_FATAL_ERROR configuration variable causes the runtime to call the MPE QUIT intrinsic when an error occurs. The MPE job control word (JCW) is then set, and the MPE environment can determine if the program terminated with a fatal error. When set to 1 (on, true, yes), QUIT_ON_FATAL_ERROR calls the MPE QUIT intrinsic. The default setting is 0 (off, false, no).
