C="This block diagram simulates waterflow in a tank. It contains a userFunction block named TANK.LEVEL that calculates the change in water content in the tank as a percentage of tank capacity. All the values are assumed to be in the same units. Change the tank capacity and initial water level in the dialog box for TANK.LEVEL.
The C source file for the TANK DLL uses the Parameter Allocation, Parameter Initialization and Parameter Change functions, as described in the VisSim User's Guide."
