Difference between data store memory(DSM) and goto-from blocks?

In which situation we need to use DSM and From/Goto Blocks?

Effect on Code and model performance?

Answer 1

[Walter Roberson]

They are completely different. From/Goto is for flow control, "Send this signal to another part of the model that I have described somewhere else". DSM holds on to information until the information is replaced, able to retrieve the information whenever it is asked for. DSM corresponds to storing something into a variable.
