The %VAL construct is used for passing arguments by value, rather than the 
usual by reference or descriptor. It is vital for interoperability with other
languages such as C.

This feature is available in g77:

http://gcc.gnu.org/onlinedocs/gcc-3.4.4/g77/_0025VAL_0028_0029.html#_0025VAL_0028_0029

My interest in this feature comes from the world of astronomy where we have
a large legacy code base (~1 Million SLOC) written in Fortran 77, (see
http://cvsweb.starlink.ac.uk) where this feature is used for efficiently
accessing large data arrays using mmap, complex data structures, and for
accessing dynamic memory.
