How to write Fortran Output as CSV file?

Question

Can any one tell me, how can I write my output of Fortran program in CSV format? So I can open the CSV file in Excel for plotting data.

Answer 1

A slightly simpler version of the write statement could be:

write (1, '(1x, F, 3(",", F))') a(1), a(2), a(3), a(4)

Of course, this only works if your data is numeric or easily repeatable. You can leave the formatting to your spreadsheet program or be more explicit here.
