I do not understand the comment that JES is unable to pass all EBCDIC 
characters.  We print Scribe output files, which use metacodes.  These 
files are effectively binary, so the fact that they print correctly 
seems to indicate that every 8-bit combination can be printed.  We 
use a separate forms type, since the 9700 must be started in a separate 
mode.  But we do not open the device directly.  The precautions that 
we have to take should not be applicable if you are really printing 
EBCDIC, as opposed to Scribe metacodes (which are in fact internal 
Xerox ASCII):
  - Be careful about DCB parameters.  I don't recall which we use,
	but if you aren't careful, JES will add trailing blanks.
	I think we use VB, with machine carriage control instead of
	ANS (to cause JES to do the minimum amount of processing).
  - If you are printing ASCII on the 9700, be careful of the ASCII
	character that looks like an EBCDIC blank.  If you end a line
	with it, JES may strip it.  (We add an extra trailing ASCII
	blank in this case.)
  - If you are printing ASCII on the 9700, do something to keep
	JES from supplying burster pages, since theese will be in
	EBCDIC.  We have hacked JES so that a certain SYSOUT class
	does not get burster pages.  Under MVS/SP, JES seems to have
	a user exit that would make this change very easy.
We are using MVS with JES2.  We have used both MVS and MVS/SP.  I 
think our MVS goes back to something like 8201.  Our MVS/SP is quite
recent.
