Comments

A real entity is an entity that holds a real scalar.

Real entities may be created in dataset or table record definitions.

Variables created in *Real() statements are assigned values in *SetReal() statements.

When *Real() statements are used in a *DefineSystem(), *DefineAnalysis(), or *BeginMDL() block, the real entity is created inside an implicitly created dataset with the variable name "Ds_Variable". These real entities are then accessed from this dataset variable name when needed, for example, 
*DefineSystem(def_sys ) 
  *Real(real_name, "Real variable", EDIT) 
  *SetReal(Ds_Variable.real_name, 100)
*EndDefine()
