The FORMOFL keyword specifies the overflow line number that will set on the overflow indicator. The overflow line number must be less than or equal to the form length. When the line that is specified as the overflow line is printed, the overflow indicator is set on.
Changing the overflow line does not require recompiling the program. You can override the number parameter of FORMOFL by specifying a new value for the OVRFLW parameter of the Override With Printer File (OVRPRTF) command.
When the FORMOFL keyword is specified, the FORMLEN keyword must also be specified.
