In this model there is two parts:
  • Part 1 is calculated for all cycles
  • Part2 is calculed for cycles 25 to 30, because temporal parameters 'Cycle' (filtering cycle) of its actions are (25-30)
    The flow 'DefaultCycle' initializes the default cycle for the model.
    The 3 following flows have floating cycle type, temporal parameters are:
  • start =1 , repeat = 3
  • start =2 , repeat = 3
  • start =3 , repeat = 3
    The function ReStartAt() allows the computation to restart at a given time unit.
    In this example, the model is compiled n times until the value of the stock "SB" is equal to the value of the stock "SD".
    The value of the stock "SD"  is function of the values of the flows "FA" and "FB".

    //Only for t=12, see temporal parameter
    //Check condition

    IF Svalue("SB")=Svalue("SD") THEN RETURN

    //Condition not ok
    //We ReStart at cycle=1 and time=1, max restart = 5

    c_restart,t_restart,Max_passing are int

    Example using the FinRepayVal() Windev function (copyright PcSoft) that returns the amount of each regular payment for an investment with fixed interest Rate and fixed payment.

    ,Term,Rate,AmountMons are currencies
    Loan= Svalue("Loan")
    Term= Svalue("Term of the loan in months")
    Rate= Svalue("Annual loan interest rate")

    Example using the FinDecreasingRedemption() Windev function (copyright PcSoft)

    //Value of a fixed rate amortization
    //The following code return an amortization value.
    //The acquisition cost and the residual value of the good, the amortization length,
    //the period over which the amortization must be calculated and the number of months

    //Variable declaration
    AmortizationValRes is a currency//amortization value for the given period
    Cost is currency//acquisition cost of the good
    ResidualVal is currency//residual value of the good after the amortization
    years is real //number of periods during which the good is amortize
    Period is int// Optional integer, period over which the amortization must be calculated (1 by default).
    NbMonth is int// Optional integer, number of months in the first amortization year (1 by default).

    Cost= Svalue("Cost")// 1000
    ResidualVal= Svalue("ResidualVal")// 100
    years= nbt//Svalue("Years")// 10

    //Calculate the amortization value
    AmortizationValRes = FinDecreasingRedemption(Cost, ResidualVal, years, Period, NbMonth)

        // Display result
        Aresult(2,"For years =",years,", the amortization value is: ",AmortizationValRes)
    AmortizationValRes = 0
            IF FinError = 0
                Aresult(2,"The amortization value is Null")
