Define the unit number of the module. Since ASPdb can be executed repeatly, the variables associated with each execution (module) are identified by a unit number attached to the end of the variable. A common mistake is to execute multiple modules without changing the dbUnit hence all the variables are mixed up. This property can also be set in dbQuickProps.

X.dbUnit=1
X.dbQuickProps= "1; NWIND;; Grid;;;;;1000;;;false;false"
