Use an existing .vdf file to load in Constant and Lookup changes. Note that both READCIN and READRUNCHG add the changes in the named files to the base model — they do not cumulate. If oldfile is empty the contents are restored to the values in the base model.
If you want to clear the list of CIN files that are in the base simulation (those which are in the "Simulate" dialog (Model->Simulate)), the Venapp command "SIMULATE>BASED|" will do this (click here for more information).
