I've just done a little more work on DIS. The changes are:

There's a new command to set the zeropoint of the gratings:
	dis grating n=? col=? zerostep=?
e.g.
	dis grating n=1 col=b zerostep=123


There's a new
	zerostep:[BR]{low,med,high}=123
keyword


I found and worked around a bug in the TDS firmware that meant that
the FILTER1 keyword was always the same. The possible values are now
	CLEAR
and
	G/R
(note that this is a change: it was previously always FILTER0.)


All of these, along with the
	dis grating n=1 type=low
command, are only present in my new version of the dis software. I
believe that we are currently running the old version --- you can check
using the
	dis status version
command. The new version is "Version 1.6  April 1998"
