Hi
How can I make my code do something depending on my compiler flag?
For example, if I use the -openmp flag I want a loop to have a
different range.
i.e.
if (flag -openmp)
do i=1,10
else
do i=1,5
endif
do loop
enddo
Thanks

You can't do that in Fortran, or pretty much any
compiled language. (I have seen it done in BASIC).
But you say compiler flag. If you use the C preprocessor,
you can do
#ifdef OPENMP
do i=1,10
#else
do i=1,5
#endif

I basically want to have different output to certain files depending
on how the user compiles the code.
I just gave the loop problem as an example. I'm also incorporating
some other features that I want to enable by compiler flags.
