Variables tags must then be linked to other objects such as block inputs and outputs using connection lines.
- You can resize a variable box vertically in order to display, together with the variable name, its tag (short comment text), its description text, plus its I/O location if the variable is mapped to an I/O channel.
The variable name is always displayed at the bottom of the rectangle:
