I'm having problems with the following constructs (created by a filter that I
have):

\h'0-\w'Dequeuing'/2u+14n'Dequeuing

	or

'nr XX 0-\w'Dequeueing'/2u+14n
\h'\n(XX'Dequeueing

The idea is to move over a certain distance and then center a given string
at that location. (Fill mode is turned off during this operation.) The
\w'foo'/2u should return half the width of the string. Subtracting that from
zero and adding 14n should place the middle of the string at 14n to the
right of where we started.

The ditroff output from the above example follows. As can be seen from the
h4488c, the string is being written off in right field rather than towards
the left of the paper where the string belongs. The font used doesn't seem
to make any difference.

Does anyone have any ideas what is going wrong with the above? I have tried
writing it in a number of different ways, none of which seem to work. Is it
something stupid on my part or something subtle?

Please reply by mail and I'll summarize anything of interest that I find out.
