Resolution:
Either specify it as an EBCDIC line sequential file if that is correct, or use MFEXTMAP"PRINTER".
Reconvert the file, ensuring that you specify Mainframe Report Format in the Organization field, and EBCDIC in the Data Format field of the Convert - Input screen. In the Convert - Output screen, the Format field is automatically set to PC Print Format when you select Mainframe Report Format in the Convert - Input screen.
