Never too soon to start fixing them. Do it one at a time.

 
Gotta do them all at once since the carriage control is controlled by
the OPEN statement.

There is a way to do it: open a second output file, without the Fortran
carriage control setting. Send both outputs to pipes read by a separate
filter process that interleaves the lines back into the real output file.

Now you can go through gradually, changing those output statements one by
one to write to the second file. Once they are all done, you can get rid
of the first file and the filter process, and resume output directly to
the output file.
