**Definition**: `syscVariableF.fi` (line 23)

Provide a struct for a System Coupling variable.

To create and/or initialize the SyscVariableF struct, it is highly recommended to use one of the functions within the `syscGetVariableF` interface . These functions will initialize all members to the correct values and will help to avoid back-compatibility issues in the future. For example:

```fortran
type(SyscVariableF) :: var
var = syscGetVariableF("Temperature", SyscScalar, .FALSE., SyscNode)

```
