I started a new project, and it called the main program "SOURCE01.f90"
I foolishly tried to change the file name to something more meaningful, but then
it would not compile it, or recognize it as Fortran file, even though I call it ENC.F90
All other fortran files I tried to add would not compile either.
When I do a Build or Rebuild it does nothing at all, and I can't run it either
because it thinks the EXE does not exist.
So why wouldn't the extension of F90 be enough to trigger a compile?
The file does not even show up as a source file, even though I can locate it
Apparently, changing the name of the MAIN program else is something that
Visual Studio can'r cope with - - -
