The first line of the description is composed by the name of the Fortran subroutine followed by its arguments.
The next lines describe Fortran variables: the arguments of the Fortran subroutine.
The description of a Fortran variable is made of its name and its type. Most Fortran variables correspond to Scilab variables (except for dimensions, see 6.3.1) and must have the same name as the corresponding Scilab variable.
Types of Fortran variables are:
Other types types also exist, that are called ``external'' types see 6.3.1.
A blank line and only one ends this description.
