WordPerfect cannot handle RTF frames; for WordPerfect, Mif2Go writes FrameMaker header and footer text without frames. When you specify WordPerfect as the output type, Mif2Go automatically sets HeadFoot to Text and HFFramed to No:
; HeadFoot = Standard, Text (no graphics), or None (for WinHelp)
; HFFramed = Yes (default) to position headers/footers using frames
