How to get pathname of currentfile with distiller

[GordonIt]

Is there any serverdict or systemdict values containing this info or something that allow to get it ?

Could be a prologue.ps modification of startup or even in distinit.ps something that would allow me to "catch" that name at run time.

I need to put the exact name in the documents trough a small PS procs
Could be derived from the PF name as distiller know it)
So "in" filename or "out" filename but acessible from prolgue is VERY valuable to me. Hot folder only is OK

Thanks
