Get variable blocks are used to retrieve the values of variables that have previously been declared and assigned to by
Set variable blocks.
Get variableblocks have one input: a string for the name of the variable we are accessing. They also have one output, which is the value of the variable we have accessed. The purpose of
Set variableblocks is to be able to store data in variables that can be accessed and modified later on in a graph's execution If no variable exists with the name that we pass to a
Get variableblock, then it will simply output no data, and any block receiving as input the
Get Variableblock's output will instead receive empty (or null) data. Refer to the
Set variableblock page for examples of
Set variableblocks in action.
