A.2 `f95` Runtime I/O Error Messages

The f95 I/O library issues diagnostic messages when errors are detected at runtime. Here is an example, compiled and run with Fortran 95:

demo% cat wf.f
      WRITE( 6 ) 1
      END
demo% f95 -o wf wf.f
demo% wf

 ******  FORTRAN RUN-TIME SYSTEM  ******
 Error 1003:  unformatted I/O on formatted unit
 Location:  the WRITE statement at line 1 of "wf.f"
 Unit:  6
 File:  standard output
Abort

Because the f95 message contains references to the originating source code filename and line number, application developers should consider using the ERR= clause in I/O statements to softly trap runtime I/O errors.

Table A–1 lists the runtime I/O messages issued by f95.
