Thanks David - I managed to get slice working ;-)

See, one of our strategies is to completely lead newbies
astray. Uh, try this:
IDL> ptr = Ptr_New(data)
:-(

Humm. This would definitely be the preferred solution.
Are you sure you are calling it correctly? It requires
a pointer to the data:
IDL> ptr = Ptr_Free(data)
IDL> Slicer3, ptr

Oh, don't even remind me of PS_FORM. :-(
Let this be a lesson to you as you become more proficient
in IDL. Don't *ever* publish your first widget program. You
will regret it all your life.
If you *have* to use SLICE (and I don't recommend that ancient
program, either), then download PSCONFIG and do a global
search and replace on PS_FORM:

If you use SLICE, be sure to set DEVICE, DECOMPOSED=0. I think
that program was written 25 years before 24-bit colors were a
reality.
