Humm. Bummer. How do you write code that works for IDL 7.1.1,
but not IDL 7.1?
Cheers,

I think the issue is not whether PS can be decomposed, it is simply
whether device can inform the state, with get_decomposed. As I
remember, this was added in 7.something. I checked in my old 7.1.1 and
it works:
IDL> print,!version
{ x86_64 linux unix linux 7.1.1 Aug 21 2009 64 64}
IDL> set_plot, 'ps'
IDL> device, decomposed=1
IDL> device, get_decomposed=state
IDL> help,state
STATE LONG = 1
IDL> device, decomposed=0
IDL> device, get_decomposed=state
IDL> help,state
STATE LONG = 0
I do not have any older versions to test.

There seems to be a documentation bug in my help file -
IDL> ?device
In the list of keywords at the top of the help window I see...
GET_DECOMPOSED (WIN, X)
If I click on the link to get to the details of the keyword I see this...
GET_DECOMPOSED
(PS, WIN, X, Z)
Regardless of the documentation confusion, it seems like a bug to me.
The language in the description of the DECOMPOSED keyword makes is seem
unambiguous that PostScript should have a decompose-able state.
Bummer.
