Data In/Out

The "data in" and "data out" items are used to initiate a flow (line) with the value of a variable, or to force a variable on output with the value of a flow:

    VarIn>- .......... ->VarOut

When used with a block, the "data in" and "data out" items can be put close to the block, without any line in-between to connect a variable to an input or output of the block.

 

In the following example, the @ symbol in front of the V variable indicates it is used for input and output.
