in this example given in the page-> Model Global Data by Creating Data Stores

Data store memory (read/write) is used for getting the Error to switch between two values.

Instead, why can't the goto- from blocks be used ?

Hi Noufal,

the main difference is, that data store memory and read/write remove the dependency between reading and writing, i.e., the data flow: you can read and write anywhere in the model at any time.

In contrast the from-goto blocks are like having a connection between the goto and the from (it's only a different representation, instead of drawing a line you use the from/goto). But the data dependency stays intact.
