For sysout data sets printed on a 3800, you can modify selected copies of output by specifying a copy modification module name in the MODIFY parameter. Copy modification allows printing predefined data on all pages of a copy or copies of the data set.
For example, you may want to vary column headings or explanatory remarks on different copies of the same printed page. Or, you may want to personalize copies with the recipient's name, address, and other information. Or, you may want to print blanks or certain characters, such as asterisks, to suppress the printing of variable data on particular copies of a page.
The predefined data is created as a copy modification module and stored in SYS1.IMAGELIB using the IEBIMAGE utility program. For information on using IEBIMAGE, see z/OS DFSMSdfp Utilities.
Copy modification is done with other printers by using short or spot carbons in the forms set.
