Type_declaration

 Explicitly specifies the properties of data objects or functions.

 Type declarations must precede all executable statements, can be
 declared only once, and cannot be used to change the type of a
 symbolic name that has already been implicitly assumed to be
 another type.

 Type declaration statements can initialize data in the same way as
 the DATA statement:  by having values, bounded by slashes, listed
 immediately after the symbolic name of the entity.
