maxscript startup access to corona values

Is it technically possible to access for example the corona passlimit via a startupscript of a corona max file.

in other terms: I have a file and when i open it i want to show the startupscript the current assigned passlimit value!

Thanks in Advance!

you can use progressive_passLimit in renderers.production
showproperties renderers.production
