Indicators OA through OG, and OV are not valid for externally described files.
Use positions 33 and 34 to specify an overflow indicator to condition which lines in each PRINTER file will be printed when overflow occurs. This entry is valid only for a PRINTER device. Overflow only occurs if defined.
Only one overflow indicator can be assigned to a file. If more than one PRINTER file in a program is assigned an overflow indicator, that indicator must be unique for each file.
