Bill and Mike, Thanks for your help. I think Mike was right about the 80-bit/64-bit compare. As Mike thought, the error occurs at a test for equality, i.e. if (x .ge. y) then I know better than to test reals for equality, but this is a closed interval test, and it still fails.

[Rd] Fortran 90 and Windows

2007-12-18 Thread Dave Roberts
I have been revising some FORTRAN 77 routines in R packages I have previously submitted. Since R is now using gfortan I experimented with some Fortran 90 code (array intrinsics primarily). So far the code is still in F77 fixed format, in files suffixed .f (not .f90), but incorporates some F90
