I guess it depends on how you parse the question. :-)
I guess I parsed it [perhaps incorrectly] as "does LAM have an mpif90"?
But yes, if you setenv MPIF77 to "f90", then yes, the "mpif77" command
will use the f90 compiler underneath. However, the wrapper will still
be named "mpif77", not "mpif90".
Hope that clarifies everything...
