A DPL script can execute a huge number of calculations in a loop. This can be used to analyse sensitivity to element or type parameters on load flow, short circuit or other calculation. This iterative looping is not fully supported for all parameters, some parameters (such as the rated voltage, rated current, rated apparent power of elements and types) are stored at the beginning (first execution of the calculation) and they will only be read again if a reset (ResetCalculation()) is forced. This behavior was implemented to improve the speed of DPL.

The not supported parameters are parameters used to build the per unit system for the calculation.
