Todd has jumped the gun somewhat, as the functionality to which he is referring in not available in the current release of MDP.
It will be available in MDP 8.5, free to those on maintenance.
The new functionality is using Date Offsets with macros, which Todd has given you the syntax for.
month has to be previous month number and not current month; can this be done in the xprj file output naming section? or some other way?
please assist; i do not (yet) want to write a vbscript or other program to rename it.
thanks a bunch in advance,
