I believe I have found a bug in OzTeX 1.3. Subscripts do not position
properly. This happens when I use PS-LaTeX 1.1(a package to automatically
substitute postscript fonts for the cm fonts), but it does not appear
when I use ordinary LaTeX.  This problem does not appear when I use
PS-LaTeX on a SparcStation, so I believe it to be a problem with
OzTeX.

Here's the problem:
$x^y$ looks like it should.
$x_y$ moves the y too far down--the top of the y is lined up with the
bottom of the x.
$x^y_z$ also looks like it should.

The workaraound is to write $x^{}_y$ instead of $x_y$, but this is a
pain because I use *many* subscripted variables.  Can some more
knowledgeable person show me how to write a macro to do this automatically?

If anyone has any ideas about this problem I'd love to hear them.
