The first one is self-explaining, use I0
or some positive number to set the field width. That is the number of characters that will be used to write the variable. Width 0
means the minimum number necessary to fit the value will be used. The A
descriptor can be left as it is. In Fortran 2008 g0
also works.
In the other case it seems that you exceeded the maximum line length. It is 72
characters in fixed-form and 132
characters in free-form. Try to split the line and use proper line continuation according to the source form.
