While on the subject of side effect of functions, is there anything in the 
(77) standard which prohibits

      PRINT *,AAP(1.)
      END
      REAL FUNCTION AAP(X)
      PRINT *,'THIS IS AAP'
      AAP = X
      END


None of the Fortrans I use properly prints this.  Yet, I find it a useful 
construct to remind me which set of functions I am using (of course only 
printing on the first call).
