063. Returning multiple values from a subroutine or function

topic: Procedures

Note

This tip is a draft1.

Fortran cannot return multiple values with syntax like

c, d = f(x)

You can use a subroutine

call f(x,c,d)

or a function that returns a derived type containing c and d or a function that returns a size-2 array if c and d have the same type.
