When you create a new source file, you have the option of fixed-form source. It's no different than building free-form source.

The only point of the first OPEN was to allow the subsequent CLOSE statement to delete the file if it existed or to error trap a problem. How should I interpret "English is poor" review when I used a language check service before submission?

Try adding: CALL SLEEPQQ(500) after the CLOSE. Mon, 04/14/2014 - 08:34 Hi Steve, I have the same problem when I am working on a machine that win 8.1 is installed. Reason, Windows may defer the actual deletion, and your OPEN to create may occur before the file is actually deleted. Quote:> Sun fortran and XLF 8.1 accept this without complaint.

Note that Windows makes it difficult to run programs that write to folders under Program Files. They have a tendency to pass test cases and then fail miserably in actual application.

Comment 6 kargl 2008-11-15 17:28:39 UTC (In reply to comment #5) > > I do believe that one could write a standard conforming "layer" in Fortran to > handle all of One point made there is that gfortran should not reposition the file after a reopen as the default position= specifier should be ASIS. While gfortran tries to provide backwards compatibility with g77, the author of g77 made several questionable choices with violating the Fortran 77 Standard. Vendors hope you will use their nonstandard convenience extension so you will not be able to use any other vendors compiler.

Mostly, because it's impossible to specify what it could mean on a wide variety of systems.
