Note: this is for Fortran 77 only. (For comp.lang.fortran readers, ignore the references about previous postings.) I am taking this up in private mail with Jim Giles. However there is one interesting point remaining: I wrote about a routine that tried to detect aliassing of input parameters. Jim wrote that failure to detect aliassing in that special case would only influence the efficiency of the code involved. However, my opinion is that any attempt to detect aliassing in a Fortran routine invalidates the code. I would like to see counter examples (because on occasion I would like to do it). So if you have a portable way to detect aliassing, mail it to me. Either I will send back a refutation or I will post the solution. -- dik t. winter, cwi, amsterdam, nederland dik@cwi.nl
