: The problem is in this section of the file:
:
: > /Top systemdict /languagelevel known
: > {systemdict /languagelevel get 2 eq}{false} ifelse {
: > currentpagedevice /PageSize get 1 get Margin sub

: > def
:
: If the file is not running in a Level 2 system, and statusdict does
: not contain an entry for paperheight, the `get' on the 5th line will
: cause an error. When control returns to the `stopped', the o-stack
: will still contain statusdict and /paperheight. As a result, the
: `def' winds up defining paperheight, not Top.
:
: This is a bug in the file, not in Ghostscript.

But why then it passes /Right ?
There file uses /paperwidth!
And why it works then if I put all these deffinitions in gs_statd.ps?
