Further to my previous posting: I should have mentioned that if you use OpProd[x:A...,y:B...]:=x y; to "clean up" the result, then you get the right answer only if Mathematica's lexcographical ordering of the operators is the same as the normal ordering of the operators that you seek, otherwise Mathematica will muck up the ordering in the final output. -- Steve Luttrell West Malvern, UK
