Well, that makes sense and "-r8 -i4" (in that order) should work. (The "-i4" overrides part of the "-r8" and options are implemented "left-to-tight".) I tried a short example and found (using "-Xlist") that the default integer is allocated just 4-bytes. If you specify "-r8", default integers are *allocated* 8-bytes, but only 4-byte arithmetic is used. This was tested with the newly released f77 5.0 compiler.
