 <a id="details" name="details"></a>## Detailed Description

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:

type(SyscVariableF) :: var

var = syscgetvariablef("Temperature", syscscalar, .false., syscnode)
