Quick Properties (dbQP) allows you to batch build all the write only properties for convenience and performance.
Obj.dbQP = "prop1=value1 | prop2=value2| prop3=p1 ! p4=x"
[|] delimites the properties
[!] delimites the keywords within the property to resolve the '|' conflict.
X.dbQP = "m=g!sysind=t | d=nwind | bm=orders | s=1| gdf=0,1,2,3"
