A minor release --- mostly fine-tuning of Fortran 90:

• some Fortran 77 features declared obsolete in F90 removed;
  
  
• HPF syntax included:
  • forall:

    DO i = 1, n !...required sequential nature an a(i,i) = x(i) ! impediment to optimisation; ENDDO

    replaced by

    forall(i = 1:n) (a(i,i) = x(i)

  • PURE procedures (functions) --- aid optimisation (with forall) further:
    • FUNCTIONSs do no alter any arguments (no side-effects);
    • no operations on external files;
    • other stuff...
  • ELEMENTAL procedures...
