FFLD Data In / Data Out

The data in and data out items are used to either:

• Initiate a flow (line) with the value of a variable.
• 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.

Example

The @ symbol in front of the V variable indicates it is used for input and output.
