The keyword representing where the right margin starts has a value that is either less than the value for left margin (LM) or it is greater than the value for the maximum presentation position (MPP). A value of 0 is also permitted and sets the right margin equal to the maximum presentation position (MPP). For more information on the keywords for the EZAPPDPF macro, see z/OS Communications Server: IP Network Print Facility. The EZAPPDPF macro is not expanded.
