This is an OPTIONAL call to pass in Header details. You may have multiple consecutive *HDR calls if you have more than five lines of header text. Header information will continue to be stored until the first *DET call. When a new *KEY call is specified then new Header information will be stored. Using *NONE in PARM1 - PARM5 will assume you want a blank line.

Note: If you want to output Header information AFTER Detail lines then you will need to pass *HDRX (extra) in PARM6 - (v1.4 or greater). This new option has been added to allow for the *HDR call to be backwardly compatible.

Header lines will be replaced on change of Header Key if using an *KEY call.
