Does FTN95 handle IO units in some unusual way? I'm testing the compiler by attempting to port over some code written using Sun's f95, and I'm getting a result that doesn't make sense to me. Specifically, I have an IO unit open for writing to an output file:

open(unit=iounit2,file=tracename,status='unknown')
write (*,*) 'Output file opened'

and then when I write to standard output further down in the code, it ends up in my output file instead. Am I doing something subtly wrong?

The value of iounit2 must not be 2 or 6.
For simplicity user values for IO units should be greater than 6.

Aha, that'd be why. Reserved unit numbers seem to be compiler-dependent. Thanks!
