The value that you specify as a variant choice from the mask dialog box popup parameter is transferred to the underneath variant subsystem block to set it choices. I want to write a script that will look in a model for blocks of a particular type, a subsystem i made, and analyze the values passed to it as dialog parameters. Specifically, the for each block enables the blocks inside the for each subsystem to process the elements of input signals or mask parameters independently. An example of this type of block is the ramp block. You will also walk through an example that outlines how to mask your subsystem in order to change its appearance.
