Please ignore the last posting by me. Overplotting
works if I save !x,!y,!z and !p and reset to those values
later.
Thanks Ken and rest of the people who responded.

Try:
!p.multi=[0,2,0,0,0]
sx=!x & sy=!y & sz=!z & sp=!p ;Save to restore later on
plot,...
sx1=!x & sy1=!y & sz1=!z & sp1=!p ;Save state of first plot
plot,...
sx2=!x & sy2=!y & sz2=!z & sp2=!p ;Save state of second plot
!x=sx1 & !y=sy1 & !z=sz1 & !p=sp1 ;Restore context of first plot
oplot,...
oplot,...
I think that all you really need to save is !x.s, !y.s, and !p.clip to
make this work, but I make it a practice of saving everything to
prevent any problems.
When a plot is produced, a data coordinate system is established and the
factors to convert between the data coordinate system and normalized
coordinates is stored in the !x.s and !y.s arrays. The oplot command
uses these values to plot the data over the current plot. When a
multiple plot is produced, the last plot command given is what sets
up the !x.s and !y.s (and !z.s) vectors. This means that further
oplot commands will be over the last plot produced unless these vectors
are reset to values for a prior plot.
The !p.clip vector is set to contain the device coordinates of a clipping
window that prevents data that maps outside of this window from being
drawn, therefore it must be changed from one window from the next. You
can also set !p.noclip=1 to prevent clipping from occurring.
I hope this helps.

Each section of a multi-page window behaves like an individual plotting
device. So for a two plot page,
plot(...)
oplot(...)
oplot(...)
plot(...)
oplot(...)
oplot(...)
should do what you are asking. I don't believe that you can oplot
to the previous plot once you've made the second plot call, though.
I'd be happy if someone could demonstrate that I'm wrong about that.
