You can use SETPRT with any 3800 or 3900 model printer allocated to the program (not to JES). You can also use SETPRT when creating SYSOUT data sets. The SYSOUT data set does not have to be directed to an IBM® 3800 or 3900 Subsystem or a printer. You can change the following control information with the SETPRT macro:

• Bursting of forms (BURST parameter).
• Character arrangements to be used (CHARS parameter).
• The number of copies (COPIES parameter).
• The starting copy number (COPYNR parameter).
• Vertical formatting of a page (FCB parameter).
• Flashing of forms (FLASH parameter).
• Initializing the printer control information (INIT parameter).
• Modification of copy (MODIFY parameter).
• Blocking or unblocking of data checks (OPTCD parameter).

Besides changing the control information, you can:

• Supply your own 3800 or 3900 load modules in a partitioned data set to replace the use of SYS1.IMAGELIB (LIBDCB parameter).
• SETPRT error messages that are sent to the printer can also be passed back to the invoking program (MSGAREA parameter).
• Print or suppress error messages on the directly allocated printer (PRTMSG parameter).
• Control the scheduling of SYSOUT segment printing (DISP parameter).
