[comp.text] Margins and VMS/Unix TeX

brian@radio.astro.astro.utoronto.ca (Brian Glendenning) (11/27/88)

Can anyone settle a trivial dispute that's going on here? We have TeX
installed on both Unix machines and VAX VMS machines. On the unix
version if you type in some tex stuff you get reasonable looking
margins. Under the vms tex you don't get any margins, that is, the
text is jammed right up against the upper left corner. \hoffset and
\voffset are the easy fix.

My guess is that the unix tex behaviour is correct, since the examples
in the TeXbook don't mention anything about having to specify margins.
The local sys_critter disagrees and says that the vms behaviour is
correct since otherwise TeX would have to guess about margins (but it
makes a lot of other assumptions, why not insert another reasonable
default??).

So, can anyone tell me what the correct behaviour is? Thanks.

(I don't know offhand what version of TeX is on the Vax, but the unix
 TeX is the standard unix distribution)

The Stanford TeX decided a while back that standard DVI drivers
should place the origin 1" from the top and 1" from the left edge
of the paper. So I suspect both TeXs are ok, it's the VMS driver
that is heretic.

Plain TeX has \hsize=6.5in and \vsize=8.9in.  This gives you a 1.0in
top, left and right margins.

So, if you are using plain TeX and you don't fool around with \voffset
or \hoffset, your text should start one inch from the top left corner
of the page.

Look up the TeXBook chapter on output routines or look up plain.tex to see
more details.
