For a program that has one or more printer files defined with an overflow indicator (OA-OG or OV), the OPENOPT keyword specifies whether the overflow indicator should be reset to *OFF when the file is opened. If the OPENOPT keyword is specified, with *NOINZOFL, the overflow indicator will remain unchanged when the associated printer file is opened. If not specified or specified with *INZOFL, the overflow indicator will be set to *OFF when the associated printer file is opened.
