The 3800 copy modification module contains predefined data for modifying some or all copies of an output data set. Segments of the module contain predefined text, its position on each page of the output data set, and the copy or copies the text applies to.

The copy modification module is created and stored in an image library, using the INCLUDE, OPTION, COPYMOD, and NAME utility control statements.

The INCLUDE statement identifies a module that is to be copied and used as a basis for the newly created module. The OPTION statement with the OVERRUN parameter allows you to suppress the printing of line overrun condition messages for those vertical line spacings that are not applicable to the job. The OPTION statement with the DEVICE parameter specifies 3800 Model 3 compatibility mode processing. The COPYMOD statement is used to describe the contents of one of the new module's segments. The NAME statement is used to identify the new module and to indicate whether it is new or is to replace an existing module with the same name.
