Thank you

As I understand, control variables are only predictors in an equation that you want the effects of other predictors to take the levels (values) of the control variables into account. If the control variables are continuous, they are treated similarly as other predictors---no specific treatment needed--just draw an arrow from a control variable to the dependent variables, among other predictor variables.
